ISOLATING SWITCH
Product description and structure
GCD isolating switch is a single-phase isolating switch on outdoor pole. It provides a visible break for maintenance personnel and can also be used
as a breaking point. The structure is a double-column isolating switch, the insulator and the bolt are locked on a hot-dip galvanized base, and the
isolating switch can be operated by pulling the pull ring. The limit of the isolation knife is 160 degrees by default (it can be changed to 90 degrees on
site or removed to no limit). When installing the GCD isolating switch, the back plate can be optionally installed, and the board can be clamped on the
crossarm to fix the switch during installation.
Technical parameter
GCD isolation switch is used in 12kV distribution network system, rated current is 630A, short-time withstand current 20KA / 4S, peak withstand current
is 50KA, power frequency and lightning impulse withstand voltage can reach the level of 2000 meters above sea level.
Safety Precautions
The person responsible for installation, maintenance and operation of the isolating switch shall have the instruction manual;
Follow your company's safety regulations;
Please read the instruction manual carefully before preparing to install, maintain and operate the isolating switch, so as not to operate the switch
incorrectly, causing unnecessary casualties;
The switch must be operated and maintained by professionals familiar with safety regulations. The right of instruction is used as a reference material for
operation and maintenance personnel, and can not be used as an alternative material for training and internship of such equipment safety regulations.
Operating
GCD disconnector is a kind of high-voltage equipment, which is usually operated with standard electrical insulation tools, and pay attention to correct
and safe operation;
The operator should use the insulated rod to pull the pull ring on the GCD. The opening and closing operation of the GCD disconnector should be
carried out under no load;
Double-post isolating switch, the insulator and bolt are locked on a hot-dip galvanized low seat, and the isolating switch can be operated by pulling the
pull ring;
The limit position of the isolation knife is 160 degrees by default (can be changed to 90 degrees on site or removed to no limit);
When installing the GCD isolating switch, the back plate can be optionally installed, and the board can be clamped on the crossarm to fix the switch
during installation.
