Overview:

GW5-40.5 outdoor isolation switch for AC 50Hz outdoor high voltage electrical equipment, rated voltage level of 40.5kV, 

for high voltage lines in

 ● each isolation switch single pole by two pillar insulators, respectively fixed on a base, 

the intersection Angle of 50° to form a V-shaped structure, mainly by

Open and close without load, and electrical isolation of high-voltage lines of electrical equipment such as 

high-voltage bus and circuit breaker under maintenance: base part, pillar insulator, connection seat part, contact head part, grounding knife, 

grounding static contact, terminal, etc.

It can also be used to open and close small capacitive or inductive currents. 

● The isolation switch is divided into three types: ungrounded, 

single grounded and double grounded. There is a mechanical interlock between the main shaft and the grounding knife, and an auxiliary switch. open

This series of outdoor isolators meet GB1985 "AC high voltage isolator and Ground switch", 

IEC60129 "AC isolator and switch switch operation mode has manual and electric two.

Ground switch "and GB/T11022" Common Technical Requirements for high voltage switchgear and control equipment standards "and other standards.

This disconnecting switch has the following characteristics:

1, flexible rotation, open and close freely. Due to the use of rolling bearing transmission, 

so in the process of rotation is more flexible, more labor-saving operation.

2, through the bevel gear mechanism to drive, so as to ensure that the two columns of the closing action is consistent.

3. Divide and close the limited position device to ensure that the contact is in the best position.

At the same time, the handle is locked by the lock ring after the operation, so as not to occur

Under the action of the external force of consciousness, the reliability of the position is guaranteed.

4, contact distance is large, there is enough margin of insulation isolation fracture, so as to ensure its safety.

5, there are three ways of grounding and ungrounding,

 there is a reliable mechanical interlock between the spindle and grounding, so as to ensure safety, users can according to the need

G W 5 - (40.5) D

Choose the grounding mode.

6, according to the user's convenience, the operation mechanism can be installed below any pole, the operation effect is the same.
