What Is This Product? – It Provides a Visible Break for Safe Maintenance
A High-Voltage Disconnect Switch Cabinet is used when you need to physically separate the power source from the load for maintenance.
This keeps workers safe. It cannot break load current (unless we add auxiliary devices).
Rated voltage is 12kV to 40.5kV.
Rated current is 630A to 2500A.
This product meets IEC 62271-102.
Inside, we put a disconnector (with a grounding switch), or a load break switch-disconnector combination.
It is often found at substation outgoing sides, transformer incoming sides, and anywhere a visible break is required.
Substation maintenance teams of China Railway and China Railway Construction use our High-Voltage Disconnect Switch Cabinet.

FAQ
What Materials and Processes Do We Use? – Metal-Clad Cabinet with a Viewing Window
The cabinet uses aluzinc steel. The disconnector compartment is separate.
The disconnector has a double-break or single-break structure. The blades are silver-plated, and contact pressure is adjustable.
The operating mechanism is worm gear or spring stored energy, with operating force ≤200N.
The door has a viewing window so you can see the contact position directly.
The grounding switch and disconnector have a mechanical interlock.
Busbars are copper with insulation tubing.
Inside, we put anti-mistake operation warning signs.
Our factory is 2,000 square meters with ISO9001 certification.

What Are the Core Advantages? – Visible Break Is Safe, with Auxiliary Contacts and Position Indication
The core selling point is absolute isolation and error prevention.
The disconnector's open/closed position is clearly indicated and lockable.
We can add auxiliary switches with up to 8 pairs of contacts to send position signals to your monitoring system.
Inside, we can put a voltage test window and a ground connection copper bar.
This product has passed type tests and meets grid safety codes.
It is perfect for railway traction substations and mining power rooms.
