To be sure all batches of 15kV dropout fuese cutout are qualified , we conduct below performance tests :

1) Power frequency dry withstand voltage test

2) Lightning impulse withtand voltage test

3) Power frequency wet withstand voltage test

4) Temperature rise limitations test

5) Radio influence levels test

Applications:

Used for distribution lines or substations up to 15kV , suitable for wooden or steel cross arm

Competitive Advantage:

we guarantee that all fuse cutout units are routine tested one by one according to IEEE C37.41 , IEEE37.42

before shipment . in this way , we can sure all product are qualified .

all related metal parts or insulation body are selected .

To offer high quality proudct is our goal .

we also advanced our design to save cost , that we can offer better price for end users.

1)  the dropout fuse cutout insulation body are high aluminum porcelain C-130 , 

2)  a layer of shinning glaze covered on the body , color can be grey or brown .

3)  the porcelain have excellent mechanical & electrical performance.

4)  Conductive parts use material copper, bronze or brass , it depends on customer’s requirement.

4)  The fuse cutout are suitable for 34.5KV lines .

Applications:

Used for distribution lines , suitable for wooden or steel cross arm

Competitive Advantage:

2 years quality insurance time are satisifed by most of customers.

to provide excellent product performance , we routine tested all porcelain body by 50% cantilever strength . for example 34.5kV dropout fuse cutout porcelain insulator Min. cantilever 15kN , we routine test 7.5kV withstand 10 seconds .

in this way , we can sure all product are qualified .
