■An overview of the

Distribution network overhead insulated process soon, but on the rod with variable area common switch, surge arrester, the grounding wire clip, pillar and other body parts in place of more brought operation point of failure, poor insulation safety conditions, installation and complex, difficult and high cost of maintenance, live working conditions such as series of problems. In response to the above problems, we must to stem some of the equipment with variable system and wiring connection, to simplify the device, further increase the purpose of he operation safety

HY5WBG-17/50 type zinc oxide lightning arrester device has the function of belt pillar, risk avoidance, puncture electricity function, check electrical grounding function of four functions as a whole, has the structure of multipurpose. HY5WDG - 17/50 type zinc oxide avoid risk unit has a pillar, lightning arrester, busbar connection with function, check electrical grounding function of four functions as a whole, has the structure of multi-purpose, to simplify the device, the purpose of further increase security.

■An overview of the

1、The ambient temperature: + 50 C;

2、Altitude: not more than 1000 m;

3、Wind speed: no more than 35 m/s;

4、Pollution level: II level;

5、No flammable, explosive and severe vibration place.

Use this device at the same time can reduce a risk avoidance device cross arm (due to the use of the originally need the backbone of the cross arm); Can reduce the vertical fixed with three of the insulator; Reduced seven skinning, namely, to reduce construction time, at the same time reduce the six point of failure, they can choose to simplify circuit device, to further increase the purpose of the operation safety and reliability, make the line more concise and beautiful. The device integrates a variety of functions, the original need seven peeling point insulation and insulation in one place, and the insulation cover design is reasonable, can be truly adventure insulation, for safety and charged job creation

■Technical parameters and the selection table

■Product features

1, the core body and the coat, lightning arrester through moulding, making it a compact whole without cavity, eliminating the respiration caused by moisture absorption, fundamentally eliminate the accidents caused by lightning arrester chip be affected with damp be affected with damp;

2, lightning arrester within the strengthening of the use of special structure, make its have good mechanical properties, can double as insulator;

3, avoid taking synthetic coat with silicone rubber material, make its uncleanness resistance is strong and has the good explosion-proof performance. In addition to reset light, long service life;

4, lightning arrester are resisted Ⅲlevel design and production of uncleanness, and its insulation coat than minimum creepage distance of 25 mm/kV.

5, lightning arrester overall structure optimized design, with functions of combination D

(1) both grounding stalk, can meet the demand of test power, grounding, can simplify tower device.

(2) the strengthening of special structure, make its have good mechanical properties, can double as post insulator.

(3) arrester device, the traditional need seven shield and in a whole insulation design.

(4) the suspension device adopts full insulation design, can effectively avoid external damage accidents, etc.

6, t HY5WDG - 17/50 arrester device has the bus wiring terminals with the function of pillar, function, check electrical grounding function, including bus terminals can be segmented cable fault, narrowing the scope of power, and the breaking of breaker with function.
