Coil electric heating cables EHC-C
Coil electric heating cables EHC-C
Electric heating cables are designed for heating of pipe fittings, nozzles of casting machines and extruders, working zones of injection moulding machines, press moulds. They are also used as heating elements in cartridge electric heaters.
Electric heaters are produced from 2 or 3 mm diameter heating cable KNMCNH-N. Cable conductor - Cr20Ni80 alloy, cable sheath - stainless steel 12Cr18Ni10T.
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
Operating and outer surface temperature of electric heater does not exceed 600°С – in running condition under heat removal with natural air convection.
