These heating cables are designed for outer heating of nozzles and working surfaces of moulding machines, extruders, press dies, and various fittings and pipelines.
Heating element is made of 
KNMSNH-N cable 2 or 3 mm diameter (Dc), H20Ni80 nichrome cable conductor, 12Cr18Ni10T steel sheath.
It is permitted to bend heating cable along the length (even to make a loop or coil) to put in required zone, if it is used in complex-geometry equipment or hard-to-get-at places. Cable can bear one bending around cylinder diameter, which equals to ten times cable diameter.
For AC or DC main connection electric heaters are equipped on default with current-carrying wires 250 mm long, made of PRKA wire in high-temperature insulation (up to 180°С). Lead length can be increased.

On customer's request electric heater can be equipped with M5 threaded contact bar. At the time of order this request should be specified as version 2
