Product Overview
A 36kV post composite insulator is an important insulating and supporting component used in medium and high voltage power systems. It is widely applied in distribution lines, overhead networks, substations, switchgear, busbar supports and electrical equipment connections. Wishpower 36kV post composite insulator is manufactured with a high-strength fiberglass core, silicone rubber housing and durable metal end fittings, providing excellent insulation performance, mechanical stability and long-term outdoor reliability.
Wishpower 36kV post composite insulator is designed to replace traditional porcelain post insulators in many power transmission and distribution applications. Compared with porcelain insulators, composite insulators offer lower weight, better impact resistance, stronger anti-pollution performance and easier installation. They are especially suitable for humid areas, polluted environments, coastal regions, industrial zones and outdoor electrical systems requiring reliable insulation support.
Main advantages of Wishpower composite insulators include:
Excellent hydrophobicity: Silicone rubber housing helps reduce surface leakage current and pollution flashover risk.
Lightweight design: Easier to transport, handle and install compared with porcelain insulators.
Stable mechanical strength: The fiberglass reinforced epoxy core provides reliable bending and supporting performance.
Good weather resistance: Suitable for long-term outdoor operation under UV, rain, temperature changes and aging conditions.
Improved operational safety: Composite structure reduces the risk of brittle fracture and porcelain breakage.
Customizable design: Voltage rating, creepage distance, end fittings, installation dimensions and housing color can be customized according to project requirements.
