Pillar arrester device
At present, the following process of urban and rural 10KV insulation process soon, but the pole on the distribution area of the widespread existence of switches, arrester, connecting clamps, pillars and other parts of the connection to bring more trouble points, poor insulation security conditions, installation complex, Difficult and high cost, poor live conditions and other series of problems. In order to deal with the above problems, it is necessary to transform some of the equipment and line connection of the pole change system so as to achieve the purpose of simplifying the device and further increasing the safety of operation. HY5WBG-17/50 synthetic jacket zinc oxide arrester device with a pillar function, arrester function, puncture power function, power test grounding function of the four functions as a whole, with a multi-purpose structure. The use of this device can also reduce the arrester cross arm (due to the use of the required pillars crossed); can reduce the vertical fixation of the three insulators; that is, to reduce the seven stripping points, reduce the number of construction time, while reducing six At the point of failure, you can achieve a simplified line device, and further increase the safety and reliability of the purpose of running, so that the line is more simple and beautiful. In addition, this device integrates a variety of functions, the original need to be stripped of the seven points of insulation and insulation in a, and this insulation cover design is reasonable, can really do the whole insulation, for safe and live operation to create favorable conditions The
