Suspension Ceramic Insulator XWP2-70

Model Description:

GB/T 7253-1987 and JB 9681-1999 standards specification (old model):

XP - Standard Type Disc Shaped Suspended Porcelain Insulator

XWP - Durable Pollution-Resistant Disc Shaped Suspended Ceramic Insulator

XHP - Glove Shell Umbrella Sulfuric Acid-Resistant Disk-type Suspenders Insulator

XMP - Grass Hat Type Durable Soil-Resistant Spherical Suspension Ceramic Insulator

Numbers 1, 2, 3... are the design sequence numbers.

The number following “—” represents the rated mechanical and electrical failure load value, in kN.

The "C" following the kN value denotes a groove-type connection structure, the "T" indicates a ball-joint cap-flange connection structure, while the ball-joint structure is not represented.

GB/T 7253-2005 Standard Specification (New Model):

U - Sway Insulator

The number following the "U" indicates the specified mechanical or mechanical failure load value, in kN.

B or C indicates ball socket or groove connection.

S or L denote short or long structural height, M indicates medium-length, and EL stands for extra-long.

P stands for large pitch.

 Note: The naming method for insulator designations in the State Grid Corporation of China's bidding documents is as follows:

1. U70B/146: U—Suspended, 70kN, B—Bushing type connection, Standard type, 146—Structure height
