Structure of a Composite Pin Type Insulator
A composite pin insulator has three main parts:
Fiberglass Reinforced Plastic (FRP) Core Rod
- Provides the main mechanical strength
- Handles bending and tensile loads from conductors and wind
Polymer Housing and Sheds
- Made from silicone rubber
- Protects the core from moisture, pollution, UV radiation, and environmental aging
- The sheds increase creepage distance to improve insulation performance
Metal End Fittings
- Galvanized steel or aluminum alloy
- Connect the insulator to the pole and conductor
Manufacturing Capability & Supply Chain Stability
Production Lines
Integral Injection Molding: Our insulators are manufactured using integral injection molding technology that minimizes the risk of moisture penetration and internal electrical failure.
Annual Capacity: With an annual output capacity of 1.1 million units, we are able to ensure consistent delivery schedules and reliable supply for large utility and infrastructure projects
Rigorous Quality Control (100% Testing)
We don't just "sample" test. Every insulator undergoes:
Routine Visual Inspection: Zero defects in the shed profile.
Tensile Load Test: Every unit is subjected to 50% of its Rated Mechanical Load (SML) before leaving the factory.
Tightness Test: To ensure the interface between the fitting and the housing is hermetically sealed.
Applications
- 11 kV to 36 kV distribution systems
- Urban and rural overhead lines
- Coastal and heavily polluted areas
- High-humidity environments
