Brown color ANSI 52-4 Porcelain Suspension Insulator / OEM available
Description:
Our insulators have externally attached caps and bases. A highly engineered cementing system transfers the load uniformly from the hardware into the porcelain body. Each insulator body is made from the highest quality clay raw materials that have been processed to be fully vitrified porcelain. The body is glazed to add strength to improve surface appearance, and enhance clean-ability.
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) | ||||||||
| 52-4 | 254 | 146 | 292 | 67 | 6 | 33.5 | 80 | 50 | 125 | 4.6 |
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.
