TML-B Submersible electric motors cable


Power cable with plastic insulation in thermoplastic elastomer sheath, is designed for submersible electric motors connection to electric network with nominal voltage of 660V,50 Hz frequency or with direct voltage of up to 1000 V.

Cable structure:

1. Copper wire conductor (5th grade of flexibility according to GOST 22483-77);

2. PVC plastic insulation;

3. Sheath - blue color thermoplastic elastomer (if customized, any color is possible).

Cable may be produced both flat and round (with R index in designation).
