Features and Benefits
Excellent High-Temperature Resistance
The cable can operate continuously at temperatures up to +180°C and withstand short-term exposure up to +250°C.
Outstanding Low-Temperature Flexibility
Remains flexible and resistant to cracking even at temperatures as low as -60°C.
Superior Flexibility
Fine-stranded copper conductors ensure excellent bending performance and suitability for moving applications.
Flame Retardant Performance
The ZR-rated construction effectively limits flame propagation and enhances fire safety.
