Control cables are multicore electrical cables used for transmitting control signals, interlocking signals, and low-level power in industrial control systems, automation panels, switchgear, motor control centres (MCCs), and instrumentation networks. They connect field devices limit switches, pushbuttons, solenoids, sensors to control panels and PLCs, and interconnect control circuits between switchgear panels in power plants and industrial facilities.

Unlike power cables, which carry the full operating current of motors and equipment, control cables carry low-level signals and control currents typically not more than a few amperes per core. The critical performance parameters are signal integrity (minimising voltage drop across long cable runs), electrical insulation quality (preventing cross-talk and earth leakage between cores), and mechanical durability (withstanding the installation conditions of the facility, including cable trays, conduits, or direct burial).

BMI manufactures LT PVC and XLPE control cables in two primary insulation grades PVC (per IS 1554 ) for standard industrial control applications, and XLPE (per IS 7098) for higher temperature environments, chemical exposure, and applications requiring enhanced insulation life. Both grades are available in armoured (with galvanised steel wire or strip armouring) and unarmoured configurations, in core counts from 2-core to 61-core, and in conductor cross-sections from 1.0 sq.mm to 2.5 sq mm — covering the full range of control cable requirements in Indian industry and infrastructure.
