Product Description
HCM-40.5 switchgear is a type of SF6 gas insulated switchgear. Its gas tank is welded with stainless steel,and it uses low pressure SF6 gas as the internal insulation medium. This gear isn't affected by external surrounding conditions at all, it runs steadily and reliably, offers strong safety protection, and has a really compact structure. What's more, it's basically maintenance free during use and has a long service life. The whole equipment is mainly made up of a few core parts, including a vacuum circuit breaker, a three position isolating switch, a busbar connection device and an electrical mechanical control device.

Frequently Asked Questions
Q1: What is the difference between HCM-40.5 and traditional air-insulated switchgear?
A: The HCM-40.5 Switchgear uses SF6 gas as the insulating medium with all live parts sealed in a stainless steel tank,while traditional air-insulated switchgear relies on air insulation with open busbars and components.
Q2: What is the MOQ of the order?
A: One set.
Q3: Is OEM/ODM available?
A: Yes.Our products can be customized as per client's requirement.
