Product Description

Introducing our High Voltage Polymer Suspension Insulators, crafted with precision and expertise. These robust insulators, made from high-grade 70kN Silicone Rubber Material, ensure superior performance.

Designed to perfection, our insulators play a crucial role in suspending conductors while keeping them insulated from towers and the earth—an indispensable component of transmission and distribution lines. With over 15 years of dedicated focus on composite insulators, Zhejiang Yuanneng Power Technology Co., Ltd. employs advanced injection and high-temperature vulcanization techniques to produce seamless, gap-free molds. Our state-of-the-art high-accuracy, large-force crimping machines ensure that the end metal fittings remain firmly attached, maintaining their integrity under standard tension loads.

With a wealth of experience, our expert team excels in designing, producing, and optimizing a wide array of insulators. Our diverse portfolio includes long rod, pin, cross-arm, post, and windproof silicone rubber insulators, each engineered to offer exceptional insulation properties and robust mechanical performance. Yuanneng insulators are the ideal choice for ensuring the reliability and safety of power systems.

Main Technical Parameters: Our insulators are meticulously crafted to meet and exceed standards such as GB/T9519-2008, IEC61109, and IEC61952.
