Distribution Lines 33kv Pin Insulator With Zinc Thread Brown BS Standard

Description:

BS standard 33KV pin type insulator technical profile shown as below table :

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

Applications:

the 33 kV pin type insulator for HV distribution lines especially in heavy pollution area .

it is very common some african countries ..

Competitive Advantage:

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 .
