Shackle Type Insulator,
High Voltage Porcelain Insulators
BS standard 33kV pin type insulator with Zinc thread brown for distribution lines
BS standard 33KV pin type insulator technical profile shown as below table :
|2||Max. Shed Diameter||mm||255|
|5||Power frequency withstand Voltage|
The 33KV pin type porcelain insulators are specially designed for South African market.
because the target market has very heavy rain , and it is coastal area.
so the insulator design should have bigger creepage distance , normally it should be more than 31mm/kV.
the product are generally used for HV voltage distributions lines.
Glaze color can be grey or chocolate brown . the insulator thread are cemented zinc thimble ,
but in this market , there are no any requirement on semi-conductive glaze .
so the insulator top are normal type design .
when insulator design ready , we need to prepare samples , and tested them according to type test items .
test items listed below:
1: Power frequency dry withstand voltage test
2: Power frequency wet withstand voltage test
3: Lightening impulse withstand voltage test ( Positive and Negative )
4: Temperature cycle test
5: Bending load test
the 33 kV pin type insulator for HV distribution lines especially in heavy pollution area .
it is very common some african countries ..
1 All of pin type insulators are well tested in our factory , test report available for customer's approval .
2 we can make stock based on customer's requirement . when they need the product , we can deliver it promptly.
3 One stop shopping , we manufacture all different type of insulators on different voltage level , so when customer make inquiry , we will provide a list of products to save customer's cost and time .
