Composite insulators are electrical insulation materials used in power transmission lines, typically composed of a core rod, an outer sheath, and metal fittings. They can be broadly categorized as follows:
There are several types of composite insulators,composite suspension insulator,composite line post insulators,composite pin-type insulators,compositecross-arm insulator,composite post insulator,composite anti-wind insulator.
Property Characteristics
Small Size, Light weight, convenient to transport and install.
Composite insulator has excellent electric properties, sheds made of silicon rubber is good at hydrophobic, transference resistance, pollution resistance and pollution flashover resistance, which makes it perform well in heavy pollution areas without human cleaning and maintenance required.
Composite insulator is good at fracture resistance, thermal aging resistance and electric resistance, good sealing protects its inside insulation from moisture.
Composite insulator has good fracture resistance and earthquake resistance, no fracture accidents occur during working time.
Composite insulator is exchangeable with porcelain insulator.
