Bowl-shaped suspension porcelain insulator with glass dome, XHP1-100

Model Description:

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

XP - Standard Type Disc Shaped Suspension Porcelain Insulator

XWP - Durable Polluted-Resistant Disc Shaped Suspended Ceramic Insulator

XHP - Spherical Insulator with Anti-Fouling Disc for Bell Umbrella Suspension

XMP - Grass Hat Type Non-Stick Dish-shaped Suspendable Ceramic Insulator

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

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

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

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

U - Suspended Insulator

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

B or C indicates ball socket or slot connection.

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

P indicates the large climbing distance.

 Note: The naming method for insulator codes 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—Structural height.

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