How many loops in the system?
Answer: normally, we will equips two loops, one loop for cable HV testing, and the other loop for power cable temperature measuring. The temperature measuring is realized via the sensor, which is buried in the cable, (up to 16 lines), User can read the temperature directly on our digital control and measuring system.
How many different structures heating transformer for cable are there in Himalayal?
Answer: for cable heating transformer, Himalayal has three different structures:
1) not open structure, normally for very small cable
2) side open structure, normally for light cable
3) top open structure, normally for heavy cable, will need crane to lifting and put the cable in.
