SF6

SF6

Because of the excellent insulation, SF6 is widely used in electrical industries, such as circuit breaker, high-voltage transmission line, CIS, large cable coil, mutual inductor, lightning arrester, electric allocating system and accelerator, wave-guide tube, and V.D. Grave generator, etc.

STANDARD OF SF6

Honghua can provide SF6 with purity of 99.8%, 99.9%, 99.99%. The product quality standard is better than that of IEC-376, ASTMD2472 or GB12022-89.
