Column insulator

High voltage pillar insulators are the core insulation support components of high-voltage substations and switch stations, mainly used to support and fix the current carrying conductors of high-voltage electrical equipment (such as circuit breakers and isolating switches), and achieve electrical insulation between conductors and grounding brackets. They are key equipment for protecting the safe operation of power systems.

Core strengths

High strength insulation material

The main body is made of electric porcelain or silicone rubber composite materials, which have excellent insulation performance, impact resistance, and heat resistance, and can withstand long-term electrical loads and mechanical stresses.

Multi umbrella skirt structure design

The umbrella skirt design significantly increases the creepage distance, effectively resisting the adhesion of rainwater and dirt, improving insulation in damp and dirty environments, and reducing the risk of flashover.

Corrosion resistance (based on actual reports), strong weather resistance

The surface of the electric porcelain is dense and smooth, and the silicone rubber has excellent hydrophobicity. It can operate stably for a long time in extreme temperatures ranging from -40 ℃ to 120 ℃, as well as complex environments such as salt spray and dust, without frequent maintenance.

Modular design, adaptable and flexible

Provide models with different voltage levels, heights, and umbrella skirt structures, which can adapt to the installation needs of various high-voltage equipment and have strong universality.
