We export huge quantity of such products to EU countries many years .

customers are very satisfied with the product quality , there are no complaints up to now .

because we control product quality very strictly .

for example :

we use high quality materials for production , that is very important :

1 the insulator metal fittings are made of high density forged steel,every pieces test qualified before using.

Flange surface are hot galvanized , zinc thickness meet related IEC and ASTM standard requirement

single point thickness are more than 85 μm. average thickness  more than 90μm .


2 Insulator shed made of HTV silicone rubber , insulator produced by high pressure injection methond . insulator core are made of high strength fiber glass ECR rod.

4 silicone sealant we sue a layer of silicone sealant cover the connection aread between metal fittings and fiber glass core, just to protect insulator have a stable performance for longer life .



This type of product mainly used for electrical switches or distribution lines up to 24kV .

Mainly for insulation support .

 Competitive Advantage:

 High quality raw material lead to high quality final product .

same quality level product , our price are most competitive .

OEM design available upon customer’s requirement or special technical specifications.
