Silicone Insulating Sleeve is extruded from high-quality silicone rubber, featuring excellent electrical insulation and weather resistance. With a wide operating temperature range of -60°C to +200°C and dielectric strength ≥20 kV/mm, it resists ozone, UV and aging, and remains flexible without hardening or cracking over long-term use. The elastic sleeve fits snugly over cable ends, wire harness connectors, busbars and battery terminals, providing reliable protection against electric shock, moisture, dust and tracking. Widely used in automotive wiring harnesses, low- and medium-voltage switchgear, transformers, EV charging stations, solar & energy storage systems and industrial electronics. Custom inner diameter, wall thickness and length are available, with optional flame-retardant, oil-resistant and color-coded versions. RoHS & REACH compliant.
