IEC 61109 Composite Suspension Insulators for 110kV-1000kV Lines

Custom SML, creepage distance, end fittings and section length for transmission lines, substations, railway systems and high-pollution environments

Optimized & Industry-ready Solutions

For All Your Power Needs

Our products use a high-temperature, acid-resistant core rod internally and are made of high-quality silicone rubber externally, resulting in high output, long service life, and lightweight construction.

We manufacture the following products: 110kV-1000kV composite long rod insulators, 11kV-230kV composite line post insulators, 11kV-800kV composite station post insulators, 27.5kV composite railway insulators; and electric fitting,
