Product Description

Product Description
Our Wholesale High Voltage Pin Type Polymer Insulators are engineered for reliable performance in power transmission lines, ideal for utility companies, electrical distributors, and infrastructure projects. Crafted from high-grade polymer materials, these insulators combine lightweight durability with exceptional electrical insulation-perfect for HV (high voltage) systems ranging from 11kV to 220kV.
Designed as a cost-effective alternative to traditional ceramic insulators, our pin type electrical insulators feature weather-resistant polymer construction that resists corrosion, UV damage, and pollution, ensuring long-term stability in harsh outdoor environments. Whether for overhead power lines, substation connections, or grid upgrades, they deliver consistent insulation and mechanical strength to support safe, uninterrupted power transmission.
As a trusted wholesale supplier, we offer bulk quantities of high voltage transformer pin insulators and custom specifications to meet diverse project needs. Suitable for both new installations and retrofits, these polymer pin insulators are easy to install, low-maintenance, and compliant with international electrical standards-making them a top choice for buyers seeking quality and value in power transmission insulation solutions.
Key Features
Robust Construction: The insulator features a strong FRP core that provides high mechanical strength and excellent electrical insulation properties.
Durable Silicone Rubber Housing: The silicone rubber housing offers exceptional resistance to weathering, UV radiation, and pollution, ensuring long-term reliability in harsh environments.
Secure Metallic Fittings: The insulator is equipped with metallic fittings on both ends. The bottom fitting, known as the pin, includes a screw for secure attachment to the cross-arm. The top fitting, or header, features a groove designed to hold conductors firmly in place.
Conditions of Use
Temperature Range: Suitable for ambient air temperatures from -40°C to +40°C.
Altitude: Effective up to 1,000 meters above sea level. For altitudes exceeding 1,000 meters, adjustments are required.
Frequency: Designed for AC power supply frequencies up to 100Hz.
Mechanical Load: Capable of handling mechanical loads up to the rated value.

Application Places
Composite Pin Insulators are designed for use in high voltage overhead power distribution systems, providing reliable insulation and support for conductors. Their robust design and materials make them ideal for:
Transmission lines
Distribution networks
Substations
Choose Composite Pin Insulators for your high voltage power distribution needs and benefit from their advanced materials and reliable performance.
