ANSI standard Porcelain Suspension Insulator normal type 52-1
Description:
Suspension insulator is one of the main type of our Orient Power product, except porcelain suspension insulator, we also produce disc suspension insulator, long rod suspension insulator, porcelain stay insulator, porcelain ,spool insulator and so on.
Specification:
| ANSI CLASS | Disc dia. (mm) | Unit spacing height (mm) | Creepage distance (mm) | Mechnical failing load (KN) | Impact strength (N.m) | Routine proof test load (kN) | Lower frequency flashover voltage | Critical impulse flashover voltage | Weight (kg) | |
| Dry(kV) | Wet(kV) | Positive(kV) | ||||||||
| 52-1 | 152 | 140 | 178 | 44 | 5 | 22 | 60 | 30 | 100 | 2.5 |
Application:
Suspension insulator can be used on power transmission and distribution overhead lines. Especially on the extreme high voltage transmission lines,it can not be replaced by other insulators.
Competitive advantage:
Reasonable insulation structure high reliability of interturn insulation.
Stainless steel flange low magnetic inductivity high resistivity.Small volume light weight.
Convenient transportation and flexible installation.
Low OSS. Low temperature rise.High mechanical strength, strong weather ability.
Outstanding crack resistance.
Low thermal expansion coefficient.
