Product Overview
Wishpower 33kV pin type composite insulator is designed for overhead transmission and distribution systems. It provides dependable insulation and mechanical support under long-term outdoor operating conditions. The product uses a composite structure to improve weather resistance, pollution resistance, and service reliability.
Key advantages include:
Excellent silicone rubber housing: Provides outstanding hydrophobicity and hydrophobicity transfer performance.
High mechanical strength: The epoxy fiberglass core rod offers reliable tensile, bending, and impact resistance.
Lightweight design: Easier to transport, handle, and install than porcelain insulators.
Strong pollution flashover resistance: Suitable for industrial, coastal, dusty, and high-humidity areas.
Reliable outdoor performance: Compact structure with good vibration and impact resistance.
Low maintenance cost: The surface is less likely to accumulate pollution, reducing cleaning frequency.
Designed for 33kV overhead lines
The insulator is suitable for conductor support and electrical isolation in 33kV distribution networks.Superior silicone rubber insulation
The silicone rubber sheds provide excellent hydrophobic performance, reducing flashover risk in rain, fog, and polluted environments.High-strength core rod
The epoxy fiberglass core rod provides strong mechanical support for overhead conductors.Suitable for harsh outdoor conditions
It can be used in high humidity, salt fog, sand, strong UV exposure, and areas with large temperature variations.Easy installation and lower construction cost
Its lightweight and compact design makes installation easier for both new line construction and old line upgrading.Excellent aging resistance
The composite material offers good resistance to UV radiation, electrical tracking, erosion, and weather aging.
Product Structure
Epoxy Fiberglass Core Rod
The core rod works as the main load-bearing component and provides high mechanical strength and bending resistance.HTV Silicone Rubber Sheds
The silicone rubber housing provides external insulation and improves pollution resistance, tracking resistance, and weather resistance.Hot-Dip Galvanized Metal Fittings
The fittings are used for connection with crossarms, brackets, or conductor clamps and provide strong corrosion resistance.End Sealing System
The sealing structure prevents moisture, dust, and contaminants from entering the interface between the core rod and metal fittings.Integrated Molded Housing
The molded housing improves material bonding and reduces the risk of aging, cracking, and partial discharge.
