Kable sterownicze niskiego napięcia
Low Voltage Control Cables, designed for low voltage industrial applications, are a particular type of electrical conductors designed to transmit control signals and power. Rated for voltage levels of 1.1 kV or lower, these cables typically provide communication between control panels and instruments in the field. Electrolytic grade copper conductors and PVC, XLPE, LSZH and flame retardant materials enable the manufacturing of our Low Voltage Control Cables, all of which are built for industrial use and will provide reliable signals and power.
Our low voltage control cables can be manufactured single core or multi-core cables as small as 0.50 sq. mm to 300 sq. mm, for a variety of control and automation applications. All of our cables are built in accordance with international standards including IS1554, IS 7098, IEC60227 and IEC60502-1 specifically to withstand the extremes of temperature, mechanical stress and electromagnetic interference conditions that are found in modern industrial facilities.
About LV Control Cables
Types of LV Control Cables
Tempsens makes various kinds of LV control cable to meet specific application needs:
- Unarmoured Control Cables: Either single- or multi-core cables with PVC, XLPE or LSZH insulation for general-purpose control applications in a protected environment.
- Armoured Control Cables: Either G.I. round wire or flat strip armoured cables (in accordance with IS 3975) to provide mechanical protection against physical damage and rodent interference.
- Screened Control Cables: Individually or overall screened with an aluminium foil with a drain wire, suitable for instrumentation circuits susceptible to electromagnetic noise.
- Flame Retardant Control Cables: FR PVC and FRLS PVC insulated cables which fulfill fire safety requirements for high-risk installation sites.
- LSZH Control Cables: Low smoke zero halogen polymer insulation to minimise toxic gas emission during a fire, which is critical for enclosed areas.
- Flexible Control Cables: A multi-strand conductor construction particularly able to withstand continuous flexing in moving machinery or robotics.

Find answers to frequently asked questions related to LV Control Cables.
LV cables are used in voltages up to a given limit of 1.1 kV; they send control signals or power to operate equipment. HV (high voltage) cables will operate at voltages above a given limit (generally above 1 kV but typically in the 11 kV-132 kV range or above), and are used to move bulk/power with increased insulation thickness and dielectric strength requirements.
LV cables generally work with identifiers from voltages of 50V to 1100V (1.1 kV); specifically, Tempsens control cables are built for a continuous rating of 1100 V as determined by the IEC 60502-1 and IS 1554 standards.
Choosing LV cable size requires calculations of the load current (using I = P/V), applying derating factors based on ambient temperature and installation method, identifying a permissible voltage drop (as a percent of the system voltage) that meets the voltage drop limits (which in practice means, it’s usually limited to below 3-5%). It’s also necessary to check a cable’s ability to withstand short circuit events, reference IEC 60228 conductor standards.
The minimum distance between HV and LV cables is commonly specified to be greater than 300 mm for unscreened cables or greater than 150 mm with a physical barrier present. All individual installations must ensure those minimum separations (or applicable separation distances) conform to local electrical codes as well as IEEE and IEC segregation guidelines to minimize interference concerns, and any overall safety concerns.
