The series of excessively-long cable

The series of excessively-long cable

Application:
ZKWD,TZKWZ,TZKWG excessively long automatic-control-temperature heating cable is specifcally used for long-distancetransport pipes, freeze-proof and thermostat, which maximum maintamning temperature is 65’℃, 105℃, 135℃. The length of singlepower circuit can reach 2000m (Bi-Power Supply can reach 4000m). It is available in the ordinary area, dangerous area and corrosive
area.The electricity-heating cable consists of three same-length single-phass series-changing box and transfonmers necessary for theinstallation (or being made accordingto the requirement of the customer, saving the phasechanging box by putting the phase-changingwire into theinner cable)

Main technical index
1. Standard colour:black,(black, red and brown for electrical heating tape sheath
2. Temperature range:the same as ZKWD,ZKWZ,ZKWG
3.Rated voltage:380-660VAC, 3 phases, 4 cores.
4、Circuit length:
