1. Product Overview
YGCP silicone rubber shielded power cables are designed for industrial power transmission in extreme environments. Rated at 450/750V AC, these cables combine high-temperature resilience with EMI protection for critical applications where standard cables fail.
2. Key Features
| Property | Specification | Benefit |
|---|---|---|
| Thermal Performance | -60°C to +180°C continuous | Withstands furnace/oven environments |
| Shielding | Copper braid (≥85% coverage) | EMI/RFI protection per IEC 60502-2 |
| Flexibility | Min. bending radius: 6×OD* | Tight routing in machinery |
| Chemical Resistance | Waterproof, ozone-resistant, mildew-proof | Suitable for harsh industrial environments |
