PTFE High Voltage Corona Resistance or CR Cables
PTFE High Voltage Corona Resistance or CR Cables
We manufacture PTFE High Voltage Corona Resistance (CR) Cables designed for demanding high-voltage applications. These cables are available in conductor sizes from AWG 26 to AWG 10 and operate reliably from 4,000 VAC up to 22,000 VAC (or 9,000 VDC to 49,000 VDC).
Key Features:
- Insulation: Corona-Resistant PTFE
- Conductor: Silver-Plated Copper (SPC), with options per customer requirement
- Voltage Rating: 4,000 VAC to 22,000 VAC / 9,000 VDC to 49,000 VDC
- Temperature Range: -65°C to +260°C
- Shielding Options: Braid or helically wrapped (served) shields
- Shield Materials: SPC, NPC, TPC, BC, SS, or custom
- Jacket: Durable PTFE in all standard electronic and bi-color options
Testing:
- Dielectric & Spark Testing: 100% length under water
- Progressive Stress Testing: Sample-based performance assurance
