SEMI-SOLID-SEALED ENVIRONMENTALLY FRIENDLY SWITCH VACUUM INTERRUPTER TD-12/630-20 (ZN-100A)

New Products / New Technology

"The 12kV semi-solid insulated eco-friendly switchgear vacuum interrupter is a core component of eco-friendly switches. Through internal structural optimization, it ensures outstanding breaking performance and internal insulation levels. The outer surface of the insulation housing is coated with silicone rubber to enhance external insulation performance, ensuring that the insulation is not compromised under the protection of dry air. It is mainly applied in medium-voltage power distribution systems, featuring high reliability, environmental friendliness, and a compact design. Standard products matched with eco-friendly switchgear and complete eco-friendly switchgear sets have successfully passed standard full-range type tests at the Xi'an High Voltage Apparatus Research Institute, fully meeting the random inspection requirements of the State Grid and China Southern Power Grid.

VACUUM INTERRUPTER FOR OUTDOOR POLE-MOUNTED SWITCH TD-12/630-20 (ZW-32B)

New Products / New Technology

The vacuum arc-extinguishing chamber for 12kV pole-mounted switches is the core component of outdoor pole-mounted switchgear, primarily designed for 12kV outdoor pole-mounted switches, including integrated primary‑secondary pole-mounted switches. Leveraging the excellent breaking and insulating properties of vacuum contacts, it provides critical protection for distribution systems. The standard product is compatible with ZW32‑type switches and has successfully passed the full set of type tests at the Xi'an High‑Voltage Apparatus Research Institute, fully meeting the random inspection requirements of both State Grid and China Southern Power Grid.

VACUUM INTERRUPTER FOR GAS-INSULATED SWITCHGEAR TD-40.5/1250-25 (TD-40.5-25Q2)

New Products / New Technology

The vacuum arc-extinguishing chamber for 40.5 kV gas‑filled switchgear is a core component of SF6‑gas‑filled switches. The sealed cabinet interior is filled with SF6 protective gas, while the vacuum arc-extinguishing chamber assumes the arc‑extinguishing function at the breaking gap. In 40.5 kV high‑voltage vacuum arc‑extinguishing chambers used in SF6‑gas‑filled switches, an innovative hybrid design separates insulation from arc‑extinguishing functions, balancing performance with environmental considerations. This design is particularly well suited to environmentally sensitive applications and is increasingly being adopted across medium‑ and high‑voltage transmission and distribution networks.
