Product Description and Structure

The GCD disconnector is an outdoor pole-mounted single-phase disconnector that provides a visible break point for maintenance personnel and can also serve as a disconnection point. It is a double-pole disconnector, with the insulator and bolts locked to a hot-dip galvanized base. Pulling the pull ring operates the disconnector. The default limit switch after the disconnector blade is open is 160 degrees (this can be changed to 90 degrees or removed to eliminate the limit switch in the field). An optional mounting backplate can be installed with the GCD disconnector, which clamps onto the crossarm to secure the switch during installation.

Technical parameters

The GCD disconnector is used in 12kV distribution network systems. Its rated current is 630A, short-time withstand current is 20KA/4S, peak withstand current is 50KA, and its power frequency and lightning impulse withstand voltage can reach the level of 2000 meters above sea level.

Safety Precautions

Personnel responsible for the installation, maintenance, and operation of disconnect switches should possess an instruction manual;

Follow your company's safety procedures;

Before installing, maintaining, or operating the disconnect switch, please read the instruction manual carefully to avoid incorrect operation that could lead to unnecessary personal injury or death.

Switches must be operated and maintained by qualified personnel familiar with safety procedures. This instruction manual is intended as a reference for operation and maintenance personnel, but cannot be used as a substitute for safety procedure training and internships for this type of equipment.

Operate

The GCD disconnector is a high-voltage device and is typically operated using standard electrical insulated tools, with careful attention paid to proper and safe operation. Operators should use an insulated pull rod to pull the pull ring on the GCD before operation. The opening and closing of the GCD disconnector should be performed under no-load conditions.

The double-column disconnect switch has its insulators and bolts locked onto a hot-dip galvanized base; pulling the pull ring operates the disconnect switch.

The limit switch after the isolation blade is opened is set to 160 degrees by default (this can be changed to 90 degrees or removed to eliminate the limit switch on-site).

When installing the GCD disconnector, a mounting backplate can be optionally installed. During installation, the plate can be clamped onto the crossarm to fix the switch.

Limiting method

Installation method

GCD disconnect switches are available in single-post and double-post mounting methods; installation methods include suspended mounting or vertical mounting; they can be installed using a single crossarm clamp or a double crossarm.

The M12 bolts on the terminals need to be tightened by the installer with a torque of approximately 80 N·m;

See the diagram below for specific installation instructions. Note the direction of the bolts.
