Suspended Porcelain Insulator XWP1-100

Model Description:

Standards specified by GB/T 7253-1987 and JB 9681-1999 (old models):

XP - Standard Type Disc Shaped Spherical Porcelain Insulator

XWP - Non-stick Dish-shaped Suspendable Ceramic Insulator

XHP - Spherical Hood Umbrella Contaminant Resistant Disk Suspension Porcelain Insulator

XMP - Grass Hat Type Durable Anti-Soiling Spherical Suspension Ceramic Insulator

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

"—" followed by the number indicates the rated mechanical and electrical failure load value, kN.

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

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

U – Suspended Insulator

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

B or C indicates ball socket or groove connection.

S or L denotes short or long structure height, M represents medium-long, and EL indicates extra-long.

P stands for large pitch.

 Note: The naming method for insulator codes in the bidding documents of State Grid Corporation is as follows:

1. U70B/146: U—suspended type, 70kN, B—socket connection, standard type, 146—structure height.

2. U100BP/155D: U—Suspended, 100kN, B—Bushing type connection, P—Corrosion-resistant, 155—Structural height, D—Double canopy

3. U160BP/170T: U—Suspended, 160kN, B—Bushing-type connection, P—Corrosion-resistant, 170—Structural height, T—Triple umbrella

4. U70C(N)/200: U-hanging type, 70kN, C-slot connection, CN-tension-resistant, ground wire insulator.
