Corona resistant PTFE insulated wires offer small size and high voltage connections in professional equipment and devices. PTFE High Voltage Corona resistance (HVCR) cables are designed for 10,000 hour life under corona.These cables offer assured reliability ,long life at high temperatures and voltages with significantly smaller diameter and weight.
WORKING VOLTAGES UP TO 14 KV AC OR 31.5 KV DC
10,000 HOURS LIFE UNDER CORONA, SHIELDED CONSTRUCTION FOR REDUCED RFI
SUITABLE FROM - 200oC TO 260oC
FLEXIBLE AND FREE FROM STRESS-CRACKING FAILURES
The size and weight of electronic and electrical equipment has drastically reduced over the years, requiring smaller and smaller high voltage interconnections in such professional equipment and devices. Corona is an ion/electron partial discharge under high electric fields, and is an inevitable consequence of conductor diameter reduction. The reduced life of insulating materials under corona imposes limitations on miniaturization and choice of materials.
PTFE HVCR cables are NOT CORONA FREE, but are designed for 10,000 - hour life under corona (shielding will help to reduce corona effects on nearby circuits).The HVCR cables are a significant advancement in technology and are recommended for "potentially" high risk applications. These cables offer assured reliability, long life at high temperatures and voltages with significantly smaller diameters and weights. ADVANTAGES OF CR PTFE
All the advantages of PTFE (except RF properties) are retained in CR PTFE: chemical inertness, Thermal/Physical/Electro-mechanical properties from cryogenic to 260oC and non-flammability. Additionally, these CR cables are free from ageing, tracking and mechanical stress-cracking failures. These designs permit much higher CW and even higher Peak/Impulse power rating.
