FAQ for Main Unit Switchgear

Q: What is a solid environmentally friendly cabinet? What is its core insulation principle?

A solid environmentally friendly cabinet is a medium-voltage power distribution equipment that uses solid insulating materials (such as epoxy resin, silicone rubber) instead of traditional SF6 gas or air as the main insulating medium. Its core insulation principle is to use the excellent dielectric properties of solid insulating materials to completely wrap and isolate high-voltage conductors, avoid air gap discharge, and at the same time, no need to fill insulating gas, achieving zero greenhouse gas emissions.

Q: Do environmentally friendly cabinets need special tools for maintenance?

No special tools are needed for routine maintenance. Daily checks only require basic tools such as a screwdriver, wrench, and gas detector. For professional inspection (e.g., gas tightness test, insulation resistance test), special equipment such as a dew point meter, insulation resistance tester, and gas leak detector is needed, which are commonly used in power equipment maintenance and can be rented or purchased from professional suppliers.
