High Voltage Line Pin Composite Insulator
Summary of composite pin insulators:
Compound needle insulators, also known as synthetic needle insulators, are common type of insulators. Mainly used in transmission and distribution lines for supporting leads and insulation. The composite needle insulator is gradually replacing the porcelain needle insulation, the market share keeps increasing.
Advantages of compound needle insulator:
Excellent resistance to bending, shock resistance, shock resistance and explosion resistance.
Light weight and high intensity.
Moistureproof performance is good.
Running maintenance is convenient. There is no need to clean up regularly and there is no zero-value test.
Not easily broken. Transportation and installation are more convenient.
Compound needle insulator manufacturing process:
The two kinds of production techniques, such as injection and moulding, are applied to the core and sheath, which can avoid the appearance of interfacial puncture.
