Features:

1) Multi-ribs of insulator eliminate flashover

2) Insulator made of 95?G pure alumina, strong resistor to shock, great mechanical

    and electric features, super insulation

3) Nickel plated housing prevents from oxidation and corrosion; heat crimping process

    ensures absolute gas-tight fit

4) Inner sealing with conductive glass ensures a fine conductivity and sealing

5) Multi-layer gaskets are elastic and strong, and reliable in sealing

6) Copper core electrode prevents from oxidation and corrosion, good electric and

    heating conductivity, long service life
