ANSI 56-5 pin insulator is high creepage distance porcelain pin type insulators with a big structure height, 13KN Rated E&M failing load and creepage distance of 865mm.
ANSI 56-5 pin insulator testings:
ANSI 56-5 ceramic pin insulator is puncture insulator used on the distribution overhead lines, and also anti-pollution insulator. The manufacturer regards an average value for puncture strength. These porcelain pin type insulators have stood high-fr ANSI 56-5 ceramic pin insulators unit is tested mechanically to a strain of suitable pounds; then it is tested electrically to flashover for ten minutes on a 60-cycle transformer.
ANSI 56-5 pin insulator,porcelain pin type insulators advantages:
1. Environmentalfriendly. At its disposal, the porcelain insulator is not dangerous waste
It is manufactured form natural materials by simple blending and curing; it may be stored in dumps with other waste. It may serve as a recycled material for the production of ceramic and similar products.
2. In comparison to the polymer, electrical strength of porcelain is higher: 25+ kV/mm v. 20 kV/mm at the polymer
The porcelain insulator in the dry state as electric insulation material has better electrical properties than the polymer, type electrical tests show better results, giving longer useful life in terms of loads generated by electric charges and other temporary electrical phenomena.
3. The porcelain insulator has demonstrably higher resistance to degradation of the surface, does not degrade or carbonate during charges; the conductive path is created very slowly in comparison of the surface of a composite-material insulator
High thermal resistance and strength, ceramics is resistant to temperatures as high as 1000°C: the surface is resistant to any type of degradation within the temperature range. The surface is stable against the effects
of UV radiation.
4. The ceramic material is resistant to rodents, termites, birds and other animals capable of compromising the integrity of polymers
The surface of the insulator is highly glazed and hard, making the product unfavourable to the tastes of the fauna.
