 Description of disconnector

GW16-72.5~245 semi pantograph disconnector Characteristics: 

It has the property of compact structure, advanced, clean appearance, beauty, Reliable property, economical.

After tripping, the vertical contact don't take up the space, especially adapt to the site that the entering line and exit line vertical different height. 
Terminal block and conductive rod is made by casting aluminum alloy and aluminum alloy section, having the advantage of high-intensity,good flowing and good anti-corrosion. 

Adapt to site's different laying way: One Line laying, 45° Laying, 135° Laying and so on 
In the galvanic circle, the section is the combination structure made by screw fix linking, having the good property of stable flowing, high reliability, simple change way and convenient adding volume way. 
In the galvanic circle, the contact and finger is made by T2Y pure copper tap whose connecting part is coated by 30μ M silver.
Finger spring is made by the stainless steel and its design is the inside hiding and outside press structure which is convenient for testing and changing 
All the operating rod and linking rod are supplied by manufacturer, which is convenient for loading, adjusting and testing. 
It can be supplied as a whole above the ground according to user's requirement.

 

Advantage:

1, Strong aging resistance

2, Long service life

3, Reasonable price

4, Porcelain uniform

5, Nice Appearance

6, Superior properties of high and low tempreture resistance, 

    mechnical capability, electrical function.  

Product structure Our company specially produces composite insulator for power transmission line, the important structure is made of shed housing, epoxy fiberglass core and metal end fittings. The surface of terminal end fittings is covered with zinc coating(hot-dip galvanization) for corrosion protection. Compared with same type ceramic and glass insulator, silicone rubber insulator has the following advantages:
(1)Small volume, light weight(is 1/7~1/10 times than ceramic insulator in the same voltage), sheds have good elasticity, not broken, convenient transportation and installation, economy.
(2)High mechanical strength. FRP ROD has high tensile strength, which is 5-10 times than ceramic materials, for core is small cross section, which makes the products small size, light weight, high tensile strength, and easy to manufacture more than 300KN large tons insulators.
(3)High antifouling property, good aging resistance performance, the sheds made of silicone rubber injection mold has good hydrophobicity and migration, which makes insulator high anti pollution flashover voltage and good electric corrosion resistance.
(4)Easy installation and maintenance, can greatly reduce outage loss which cause due to maintenance and maintenance charges which cause by manual labor intensity.
(5)Simple production process, short delivery time.
