Suspended Porcelain Insulator XWP1-160

Model Description:

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

XP - Standard Type Disc Shaped Suspended Porcelain Insulator

XWP - Non-stick Disk-shaped Sway Type Porcelain Insulator

XHP -污染 resistant, dome-shaped suspended porcelain insulator

XMP - Grass Hat Type Foul-Tolerant Dish Shaped Suspension Porcelain Insulator

Number 1, 2, 3... represent the design sequence numbers.

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

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

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

U - Sway Insulator

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

B or C indicates ball and socket or slot-type connections.

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

P stands for large climbing distance.

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