Silicone Rubber Overhead Line Cover for overhead lines is engineered from premium silicone rubber, offering exceptional insulation, weather resistance, mechanical strength, and elasticity. Featuring hydrophobicity and stability across a wide temperature range (-50 °C to +150 °C), it ensures reliable performance in harsh environments. Its innovative snap-on design enables quick, tool-free installation without power interruption, making it ideal for live-line applications. Suitable for overhead systems from 1 kV to 220 kV—including power grids and electrified railways—this sleeve enhances insulation in areas where conductors cross forests, buildings, or tunnels, preventing leakage, creepage, and electrical accidents. It also provides effective protection against bird nesting, lightning strikes, and ice accumulation, supporting safer and more resilient grid operation.
Core Features:
Wide Temperature Tolerance: Operates reliably from -50 °C to +150 °C.
Superior Electrical Performance: Electrical strength ≥22 kV/mm, volume resistivity ≥2×10¹⁴ Ω·cm.
Hydrophobic & Anti-Aging: Repels water, resists pollution buildup, and withstands UV/ozone exposure.
Snap-On Sealed Structure: Allows easy, non-interruption installation; closes into a fully sealed insulation layer.
Multi-Size Compatibility: Inner diameters from 16 mm to 32 mm, fitting common high-voltage bare conductors.
Key Applications:
Insulation Enhancement: For bare conductors crossing forests, buildings, tunnels, etc.
Bird Protection: Prevents nesting and short circuits caused by bird droppings.
Lightning & Icing Mitigation: Improves insulation against overvoltage; buffers mechanical stress from ice load.
Critical Installations: Substation entries/exits, railway catenaries, urban distribution networks, and mountainous transmission corridors.
Ideal for utility “Comprehensive Bird Harm Management” projects and harsh-environment upgrades, this Silicone Rubber Overhead Line Cover combines long-term durability with maintenance-free operation, strengthening grid safety and reliability.
