Product Description

Introducing our robust High Voltage Polymer Suspension Insulators, crafted from premium 70kN Silicone Rubber Material, designed to elevate performance and reliability.

Our Insulators play a crucial role in suspending conductors while ensuring they remain insulated from towers and the earth—integral components of transmission and distribution lines. With over 15 years of expertise, Yuanneng excels in crafting composite insulators using advanced injection and high-temperature vulcanization techniques. This meticulous process ensures a seamless mold without gaps. Utilizing high-precision, large-force crimping machines, we assure that the end metal fittings remain intact and secure during standard tension loads, guaranteeing unparalleled durability.

Leveraging our extensive experience, Yuanneng is adept at designing, producing, and optimizing a wide array of insulator types. Our portfolio includes long rod insulators, pin insulators, cross-arm insulators, post insulators, and windproof silicone rubber insulators. Each product boasts superior insulation properties and robust mechanical performance, making Yuanneng insulators your optimal choice to ensure the reliability and safety of power systems.

Main Technical Parameters: Our products are engineered to meet the stringent standards of GB/T9519-2008, IEC61109, and IEC61952, promising exceptional performance and reliability.
