Product DescriptionThe main function of the arrester is to protect
electrical equipment from lightning intrusion wave overvoltage and
operating overvoltage to damage the insulation of its equipment.
Zinc oxide arresters are arresters with good protection
performance. Utilizing the good nonlinear volt-ampere
characteristics of zinc oxide, the current flowing through the
arrester at normal operating voltage is extremely small
(microampere or milliampere level); when the overvoltage acts, the
resistance drops sharply, and the energy of the overvoltage is
released. To achieve the effect of protection. The difference
between this arrester and the traditional arrester is that it has
no discharge gap, and uses the nonlinear characteristics of zinc
oxide to play the role of leakage and breaking.Composite jacket:
Composite jacket zinc oxide surge arrester is made of composite
silicone rubber material, and high-performance zinc oxide resistors
are selected. The interior adopts a special structure and is
assembled by advanced technology. Double advantage. In addition to
all the advantages of zinc oxide surge arresters with porcelain
jackets, this series of products also has good insulation
performance, high pollution resistance, good explosion-proof
performance, small size, light weight, no maintenance at ordinary
times, not easy to damage, reliable sealing, durable Excellent
aging performance and other advantages.The zinc oxide arrester has
simple structure, good protection performance, large flow capacity,
low residual voltage, and wireless flow. According to its rated
voltage, it is divided into several types such as 0.28, 0.5, 7.6,
12.7, 41KV and so on. Because it protects both atmospheric
overvoltage and operating overvoltage. Therefore, it is widely used
in 10KV and below transformation and distribution systems, such as
distribution transformers, instrument transformers, cables and
vacuum circuit breakers.Model DescriptionProduct technical
