A composite long rod insulator is made of silicone rubber, test results on the electrical and mechanical properties are reported that it has many advantages, such as light in weight, easy of manufacture, high mechanical strength, better antipollution performance, less risk of internal puncture, and much reduced for service safeguarding. These advantages become more obvious in transmission and districution lines.
Core: Longrod insulators are manufactured with electrical grade corrosion resistant epoxy rod, The materails used are of the best quality and are routinely tested to ensure the maximum performance characteristics.
End fittings: A range of end fittings are available to provide fliexible coupling methods that integrate into each line design, The fittings are machined from malleable cast iron and hot dip galvanised in accordance with ISO1461.
Sheds: The sheds are manufactured using high-pressure injection moulding technicques to create a smooth surface reducing the amount of pollution trap.
Leakage distance: HTV silicone rubber is used for the shed manufacture, the materila is highly filled with ATH to resist tracking and a silicone base polymer to provide the hydrophobicity, which is transforred to the pollution layer.
Standards: Most of the insulators are manufactured in accordance to IEC 61109.
Design flexibility: Except the standarded insulators, can be offer flexible solutions to customer requests, with the more than 20 years experience in the industry.
