Product Description

GW5 V-shaped 40.5kv 630A 1250A Outdoor high-voltage Porcelain Isolation Switch

GW5 type isolation switch is a switch in the no load flow conditions for high voltage transmission line,and the high voltage bus,is maintenance of the circuit breaker and other electrical equipment and charged high electrical isolation in,in the main switch in the normal brake position-provide a meet safety requirements can see insulation distance.
 

Meet the GB1985"IEC-129"AC isolation switch and the isolating switch(1984)" and the earthing switch" standard AC isolation switch.Therefore, it is reliable, safe operation; and has the advantages of small volume, simple structure, convenient in stallation and debugging.Consisting of three monopoles and mechanism, each single pole, isolating switch consists of two post insulator are respectively fixed on a base,an angle of 50 degrees into a V type structure,one side of the body to rotate through a porcelain vases.bevel gear switch in the base.The main circuit adopts copper material,local two silver plated contact,contact,through flow capacity,operating mechanism adopts CS17 manual mechanism,light and flexible,there is a mechanical interlocking mechanism design between the output shaft, and can be equipped with electromagnetic lock, can ensure that the anti misoperation, also can be equipped with CJ11type electric operating mechanism,In order to facilitate the different user requirements. Is a high-voltage electrical products cheap,widely used in power plants and power plants.

 

Normal Service Conditions
1.The altitude does not exceed 1000m;
2.The ambient air temperature: Maximum+ 40ºC ;Minimum:General Area -30ºC, Paramos -40ºC;
3.The earthquake intensity does not exceed 8 degrees;
4.Installation Location: No fire, explosion danger, pollution, chemical corrosion and frequent violent vibration of the place.

Features:
The isolating switch adopts a double-column center-opening and contact-turning structure, which has the ability of self-cleaning contacts and improves contact reliability; the contact fingers are made of new materials with high strength, high conductivity and high elasticity. Relying on the elastic force of the contact finger itself to clamp the contact, avoiding the current vicious cycle of reduced contact clamping force, increased contact resistance, increased contact resistance, and aggravated contact heating caused by spring corrosion and heat annealing; the isolation switch rotates Some are designed according to maintenance-free requirements. The rotating seat is designed as a sealed structure, so that water vapor, dust, and harmful gases cannot enter, so that the bearing and molybdenum disulfide lithium-based grease will always work in a good environment, the bearing will never rust, the grease will never be lost, and it will never dry up. The operating torque of the isolating switch will not increase after long-term action. The stainless gold crankpin and oil-free self-lubricating bearings are used in combination; the steel parts are hot-dip galvanized to ensure that the isolating switch is flexible, light, reliable, and rust-free.
