Descriptions:

1.Multi-ribs of insulator eliminate flashover
2. Nickel plated housing prevents oxidation and corrosion, heat crimping process ensures absolute gas-tight fit
3. Inner sealing with conductive glass ensures a fine conductivity and sealing 
4. Multi-layer gasket are elasticity strong, and reliable in sealing
5. Copper cored electrode prevents oxidation and corrosion, good electric and heat conductivity, long service life
