GARG Advantages: - Long life at high temperatures and voltages with significantly smaller diameters and weights
- HVCR cables are free from ageing, tracking and mechanical stress-cracking failures.
- GARG designs permit much higher CW and even higher Peak/Impulse power rating.
- In some recent tests on long samples of AWG 18/19/30 X 10 CR, rated at 16 KV AC/36 KV DC, repeated application of HV DC of 140 KV did not cause any breakdown
- SELECT GRADED (SG) HVCR cables for up to 30% higher ratings or longer life (than our normal cables of the same size), for critical applications, are available on demand
- Custom design solutions available
Performance and Quality Assurance We have been manufacturing HVCR cables for more than 35 years. There are no generally accepted specifications for HVCR wires & cables. We have developed various performance and testing methods. To read more about our performance and testing click here |
