Composite Pin Type Insulators
Product Description
Differences between suspension and polymer pin insulators:
Suspension insulator tensile strength is very big, can put a number of connection string, increase the compressive strength, to adapt to a variety of different voltage grade line, generally available in the line of resistance to a period of use, or hanging wires used post pin insulator only a single independent support conductor, general is in the middle pole support for conductor, due to the problem of pressure limit, can only be used on the lines below 35 kv.
Product Parameters
Raw Materials:
1) Silicon Rubber for sheds and housing
2) Glass-fiber reinforced epoxy resin rod (ECR type) for core
3) Hop dip galvanized cast steel for metal fittings
4) 5000h aging test.
5) IEC Standard
Product Advantage:
Composite pin insulator has high resistance to bending, impact, shock and explosion.The inner insulation is reliable and light weight, which is an ideal replacement for the traditional tempered glass insulators.
Electrical Performance Of Pin Polymer Insulator:
The destructive discharge along the insulation surface is called flashover. Flashover is the main electrical performance of pin insulator.For different voltage levels, the voltage tolerance requirements of pin insulators are different, and the indicators include power frequency dry, wet voltage, lightning shock voltage, lightning shock carrier voltage, operating shock voltage and so on.To avoid breakdown in operation, the breakdown voltage of the insulator is higher than the flashover voltage.
