Radiation XLPO insulated Control Cable is not cross-linked by normal chemical cross-linking material under high temperature and high pressure, but cross-linked by high energy electron accelerator or rays. That is why radiation XLPO insulated control cables get higher electrical property, excellent flame retardant property, Stronger mechanical property, they are also with better resistant to heat-aging, scratching, abrasion, oil, melting, and environmental stress crack. The most common material used for radiation cross-link cables are PVC, XLPE.
Product features
Long-term temperature: Up to 125℃
Conductor: OFC copper
Heat-resistant level: 90℃,105℃,125℃
Rated voltage: Up to 0.6/1kV
Application
This cable is used in control system, electrical equipments and instruments, especially suitable for high temperature and fire retardant condition.
