Pre-Molded (PM) Series Cold Shrink Accessories
As a cable accessories manufacturer, we offers a range of cable accessories to meet medium voltage, high voltage, ultra high voltage and extra high voltage requirements.The Pre-Molded (PM) series of cold shrink medium voltage cable accessories are high-end products available for extruded dielectric power cables from 8.7kV through 35kV and up to 630mm2.
State-of-the-art software is employed to perform electric stress analysis and optimization which ensures the electric stress of these cable accessories is distributed in the most rational way. Liquid silicone rubber is used as the raw material, which greatly improves the mechanical and electrical properties of this product. This allows installation in various kinds of complicated environments, resulting in simple, reliable installation and excellent product performance.
Features and Benefits
- • Liquid silicone rubber (LSR) is used for outstanding electrical conductivity and insulation
- • Employs design concepts used for high voltage stress control
- • Hydrophobic and highly UV resistant for excellent performance in outdoor applications
