LSR has become the core insulation material for cable accessories due to excellent electrical insulation and processing precision.
Cable accessories (cold-shrink/hot-shrink terminations, joints) are critical components in power transmission systems. LSR has become the core insulation material due to excellent electrical insulation, weather resistance, and processing precision.
For cable termination and joint main insulation, volume resistivity greater than 1x10^15, typical hardness 40-50 Shore A
For stress cones and stress control layers, high permittivity (8-15), non-linear resistance characteristics
For shielding layers, volume resistivity 10^2 to 10^5 ohm-cm, carbon black filled
For outdoor terminations, UL94 V-0 rating, aluminum hydroxide/platinum catalyst system
LSR applications in cable accessories continue to expand. Correct material selection and strict process control are essential for long-term reliability. With grid upgrades and renewable energy development, high-performance LSR cable accessories face growing market opportunities.
