Transmission and distribution line post insulator is one of electrical insulator in high voltage overhead power line.

transmission and distribution line post insulator

Orient power can supply transmission and distribution porcelain line post insulator and composite line post insulator.

How about the application for the line post insulator?

Transmission and distribution line post insulator types using voltage under 132KV , the function is same with pin insulator , the line post insulator one side is connect with conductor , the other side for ceramic line post insulator fixed in the cross arm .

Transmission and distribution line post insulator have tie top and clamp top type ,and the mounting direction, have horizontal or vertical.

The classification for porcelain or ceramic line post insulator:
According to the types of connecting with conductors, transmission and distribution ceramic line post insulator can be classified into:
Tie top line post insulator: ANSI 57-1, ANSI 57-2, ANSI 57-3, ANSI 57-4, ANSI 57-5
Clamp top line post insulator, vertical clamp mounting direction: ANSI 57-11, ANSI 57-12, ANSI 57-13, ANSI 57-14, ANSI 57-15
Clamp top line post insulator, horizontal clamp mounting direction: ANSI 57-21, ANSI 57-22, ANSI 57-23, ANSI 57-24, ANSI 57-25
Clamp top line post insulator, inclined horizontal clamp mounting direction: ANSI 57-31, ANSI 57-32, ANSI 57-33, ANSI 57-34, ANSI 57-35

The cantilever strength of porcelain line post insulator can be 5KN, 10KN, 12.5KN, 16KN.

Composite transmission and distribution line post insulator as it is made of the FRP core, silicon rubber housing and metal end fittings, so it is have better mechanical load, can displace the porcelain line post insulator well .

Orient power can supply kinds of transmission and distribution line post insulator , also the line post insulator have the type test report and sample test report , can do line post insulator according to customers' requirements , welcome to inquiry us !
