HY5WZ-51/134E Zinc Oxide Arrester with Electrical switchgear euipment 1. The difference between lightning arrester and lightning rod is that lightning arrester is a part, a kind of equipment, and has its own function. The lightning rod is an integral part of the system, which is made of round steel, and the connecting wire and grounding wire together form a system to perform lightning avoidance function. The concepts are as follows: 2. The lightning arrester is an electrical

HY5WZ-51/134J Zinc Oxide Lightning Arrester with Electrical switchgear euipment The lightning arrester is an electrical appliance used to protect the electrical equipment from high transient overvoltage and to limit the duration of continuous flow. The term includes any external clearance necessary for the normal functioning of the appliance at run time, whether or not it is a component of the whole. The lightning rod is to install a metal rod at the top of a tall building,

HY5W-3/10 Zinc Oxide Arrester with Electrical Switchgear Euipment Description: The CPD test is similar to the general pressure test, except that the CPD voltage is not fixed, but is raised to the lightning arrester discharge. It is advisable to cut the power supply at the rate of 3 ~ 5 000 volts per second, so it should be installed in the test circuit. Testing of ZnO arrestors MOA is a new type of overvoltage protection equipment, which has better protection performance than
