220KV composite suspension insulator is a common composite insulators type, and 70KN 220KV composite suspension insulator is just one of them divided by mechanical strength.

220KV composite suspension insulator Materials:
1) Silicon Rubber for sheds/ housing
2) Glass-fiber reinforced epoxy resin rod (ECR type) for core
3) Hop dip galvanized cast steel for metal fittings

Fiberglass rod of 70KN 220KV composite suspension insulator is high mechanical tensile strength, in general can up to 600Mpa or more, meanwhile, against bending fatigue fracture, anti-impact and good electric insulation. In addition to 70KN, 220KV composite suspension insulator also can be designed and manufactured into 120KN, 160KN and so on.

Metal fitting of 70KN 220KV composite suspension insulator connects with core rod by pressure, there are features as follows: not break integrity of core rod, high tensile strength and small dispersivity for tensile break strength and so on.

Grading ring used 220KV composite suspension insulator is made by light aluminum gold, which improve electric field distribution arc starting and protect terminal metal fitting and shed housing from ablating by hard arc partial developed. 70KN 220KV composite suspension insulator usually use two grading ring.
