Description
Description
The Composite Needle-Type Insulator is a high-performance electrical component engineered for medium and high-voltage power distribution systems. Designed to provide exceptional electrical insulation and robust mechanical support, it is the ideal choice for compact line structures where reliability in harsh environments is non-negotiable.
By integrating a high-strength fiberglass reinforced epoxy resin core with a hydrophobic silicone rubber housing, this insulator minimizes leakage current and prevents flashovers. Its specialized needle-type design maximizes creepage distance, ensuring stable operation even in highly polluted, humid, or saline atmospheric conditions.

Frequently Asked Questions
Q: What are the main benefits of composite insulators over porcelain ones?
Composite insulators are lightweight, have superior hydrophobic properties to prevent flashovers, and offer higher resistance to mechanical impact and environmental pollution compared to traditional porcelain.
Q: How does the "needle-type" design improve insulation?
The needle-type design utilizes specialized sheds to increase the creepage distance. This lengthens the path electricity must travel over the surface, reducing the likelihood of leakage current and flashovers.
Q: What is the role of the silicone rubber housing?
The silicone rubber provides the external electrical insulation. Its high hydrophobicity prevents the formation of continuous water films, making it ideal for humid or coastal environments.
Q: Can these insulators withstand high mechanical loads?
Yes, the core is made of fiberglass reinforced epoxy resin, which is specifically designed to handle high tension and bending loads, ensuring structural integrity for overhead lines.
Q: Which voltage levels are supported by these composite insulators?
Our range supports medium to high voltage applications, typically covering ratings from 10kV up to 36kV, depending on the specific model selected.
Q: How do these insulators perform in polluted industrial areas?
They perform exceptionally well. The combination of hydrophobic silicone and extended creepage distance prevents pollution layers from causing electrical tracking or flashovers.
