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.
