The Solar DC cable is a special single core copper conductor designed to transfer DC current directly to the PV system. These are made from annealed tinned copper conductor with cross linked insulation.

Based on installation distance and current specifications, choosing a right size for the solar panel’s DC cable is critical. The sizing chart contains wire sizes from 1.5 square millimeters (19 Amps) for small scale residential applications up to 240 square millimeters (520 Amps) for commercial use; typical wire sizes would be 4 square millimeters (42 Amps), 6 square millimeters (52 Amps), 10 sqmm (76 Amps) or 16 sqmm (95 Amps), depending on the number of panels and their capability.

The price of DC solar cables will depend on the size of the conductors, the type of insulation used, and how many cables are ordered. The actual pricing will be affected by the cross-sectional area of the conductors, which can range from 1.5 to 240 sq.mm, the specifications used to build each conductor (e.g., tinned copper, LSZH/XLPO insulation), and other standards that must meet BS EN 50618: 2014. You can also contact Tempsens for competitive quotations based on the unique specifications of your solar photovoltaic cable.

Lead wire provides connectivity between instrumentation(thermistors, resistors) and electrical components(LED, heaters) in places such as control panels, chemical plants, laboratories, and industrial heating systems that require specialized insulation and high temperature resistances for their use.

No. The lead wire is a connecting wire used in industries insulated with materials like PVC, PTFE polymers etc.

A lead wire’s longevity is affected by many things: operating temperature, conditions of the environment, and the insulator used. Under rated operating conditions, the PVC insulated lead wires from Tempsens will generally last for 15 to 20 years, whereas PTFE and FEP insulated lead wires may very well exceed 25 to 30 years of lifespan.

Lead Wire is frequently referred to as Hookup wiring, Connection Wiring or Conductor Wiring. Depending on the settings of various temperature measuring applications, the lead wire may be identified as Extension Wire or Compensation Cable.

The lead wire price is determined by the conductor size, insulation material, and specifications. The quality of lead wires offered by Tempsens is of the highest standard at prices that are competitive with the marketplace, and their quotation for each type of lead wire will be provided upon request.

Low voltage cables are used up to and including a maximum value of 1.1kV (1100 volts). LV cables made by Tempsens are designed specifically to operate within a maximum voltage rating of LV for applications such as industrial and commercial users of electricity that need dependable power transfer without exceeding the design criteria for medium voltage equipment.

LV (Low Voltage) cables operate at voltages of 1.1kV and below, and are generally used to wire buildings and supply electricity. MV (Medium Voltage) cables operate at voltages between 1kV and 35kV, and are typically used in distribution systems of electric utilities. HV (High Voltage) cables operate at voltages greater than 35kV, and are used for the transmission of electricity over long distances; they require specific insulation and design for improved performance under varying degrees of electrical stress.

A low-voltage power cable is composed of copper or tin plated copper (from 0.50 mm² to 300 mm²) as electrolytic grade conductors, core insulation made from either PVC, XLPE, or LSZH materials, a screen of either aluminium foil or mesh braid coverings used on the shielded variants, both the inner & outer sheaths protect the core from environmental damage; also available G.I. armour (metal-woven covering) for additional mechanical and impact resistance for difficult installations.

The various types that Tempsens uses include PVC (Polyvinyl Chloride) for standard installations, XLPE (Cross-Linked Polyethylene) to withstand higher heat exposure (up to 90°C), HR PVC (Heat Resistant PVC), LSZH (Low Smoke and Zero Halogen) polymers for fire safety, FR PVC and FRLS PVC, which are flame retardant, along with PE (Polyethylene) or XLPO are used for some extreme applications that comply with IS & IEC Standards.

High temperature cables utilize select types of insulation made from materials including PTFE, fiberglass, ceramics, silicone rubber, or alumina fibers.

The operating temperature ranges for the various types of insulation are: alumina fibers can handle up to 1200°C; ceramic fibers can handle up to 800°C; fiberglass can handle up to 550°C; polyimides can handle about 310°C; PTFE and PFA cables can handle up to about 260°C; and silicone rubber has a maximum operating temperature of about 180°C.

The conductor materials for high temperature cables are selected from among annealed bare copper, tinned copper, silver plated copper, nickel plated copper, pure nickel, and NPC 27% alloy based on the temperature and performance of the application.

Operating temperature, voltage grade, conductor size, environmental factors, chemical exposure, degree of flexibility required and relevant standards must all be taken into consideration when selecting a high temperature cable. Refer to the manufacturer’s specifications for assistance in making the best selection.

Heat resistant cables should be chosen based on maximum operating temperature, voltage requirement, conductor size based on current load and environmental exposure (chemicals).

A heat-resistant cable can endure continuous high-temperature service (between 200°C – 800°C) whereas Fire Resistant Cables keep circuit integrity during a fire at “normal” temperatures.

Tempsens cables are designed for continuous use and have a service life of more than 20+ years when installed correctly and within the rated parameters provided by IS 8130.

The flexibility depends on the type of insulation – the silicone and FEP have very high levels of flexibility, while the fiberglass and ceramic fiber will offer average flexibility based on the requirements of the application.

Fire-retardant cables resist initial ignition and slow the spread of flames. Fire-resistant cables are designed to stay functional for limited time periods during a fire event. Fire survival cables are designed to ensure full circuit integrity at temperatures exceeding 750°C for 30-180 minutes, thereby keeping essential emergency safety systems operational throughout and subsequent to varying emergency fire events.

Installation must account for minimum bending radius (6-8 times cable diameter), use of fire resistant/cable retention fixings, adequate segregation away from other cables, fire rated terminations with cable duration rating, and qualified installation per BS 7671 regulation in order not to compromise fire survival integrity.

MI cable is a sheathed Thermocouple Cable, having an outer sheath of metal with Two to Eight Cores where positive and negative thermo elements run around Circular Pattern, embedded in MgO. Mineral Insulated Cables are suitable to high Mechanical, Chemical, and Electrical stability. Due to good Flexibility, Excellent mechanical strength, and pressure resistance, mineral insulated Thermocouples/RTD’s can be installed in complex installations.

Construction:

• One or more wire like conductors (cores) are embedded in a high insulation quality MgO(Magnesium Oxide) and pressed into a metal tube (sheath) made of oxidation and corrosion resistant material. The entire combination is then processed using suitable forming steps to obtain the final dimensions.

Compensating cable is made of alloys which are different from those of thermocouples but have the same output over a limited temperature range. Compensating cable is a connector between thermocouple and measuring instruments, these cables are less precise, but cheaper. They harness quite different relatively low cost alloy conductor materials, whose net thermocouple in question. The combination develops similar output as those of the thermocouple, but the operating temperature range has to be restricted to keep miss-match error acceptably small.

MI Cables cover up the wide area of applications. Important are listed below:

• In Chemical, Petrochemical and fertilizer industries, and as equipment in dairy, food processing, pharmaceutical industries, in hospitals, households as kitchenware, cryogenic vessels and as heat exchanger in air conditioning refrigeration, for machinery in paper, pulp and textile beverage sector.
• Architectural trims, Marine exteriors, chemical processing equipment, food processing equipment, petroleum refining equipment, photographic equipment.
• Nuclear power and reactor construction, chemical apparatus engineering, annealing furnaces, heat exchangers, crude oil industry, grease and soap industry, aircraft exhaust stacks and manifolds, pressure vessels, large mufflers for diesel engines, carburetors, expansion bellows, stack liners, fire walls etc.
• Power technology, recuperates, heat treatment kilns, vortex firing installations, waste incinerators, furnace construction, boilers and blast furnaces, PWR, Space Travel.

Extension cable uses wire of nominally the same conductor as the thermocouple itself, which thus inherently possess similar thermo power characteristics, and with no connection problems. Miss-match error arising from high connecting box temperature is likely to be relatively small. These cable are less costly then thermocouple wire, although not cheap, and are usually produced in a convenient form for carrying over long distance typically as flexible wiring or multi-core cables.They are recommended for best accuracy.
