China Arrester and Protection Device Factory

"JECSANY" is a professional China various medium and high voltage product provider which supplies surge Arrester and Protection Device, vacuum circuit breakers, auto reclosers, switchgear, dropout fuses, polymer/porcelain insulators, power tools, power accessories, OPGW/ADSS, distribution transformers, etc. And be able to provide one-stop service for new and old customers, including product development, design, manufacturing, transportation, installation, and after-sales service.

There are many kinds of arresters, including metal oxide arresters, line-type metal oxide arresters, gapless line-type metal oxide arresters, fully insulated composite jacketed metal oxide arresters, and detachable arresters.
The main types of arresters are tubular arresters, valve arresters and zinc oxide arresters. The main working principle of each type of arrester is different, but their work is essentially the same, all to protect communication cables and communication equipment from damage. Zinc oxide arrester is a lightning arrester with superior protection performance, light weight, pollution resistance and stable performance. It mainly uses the good nonlinear volt-ampere characteristics of zinc oxide, so that the current flowing through the arrester is extremely small (micro-amp or milli-amp level) under normal working voltage; when over-voltage acts, the resistance drops sharply, discharging the over-voltage energy for 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 interruption.

The lightning protection grounding device includes the following parts:
1) Lightning receiving devices: metal poles (air-termination devices) that directly or indirectly receive lightning, such as lightning rods, lightning protection belts (nets), overhead ground wires and lightning arresters, etc.
2) Grounding wire (down-lead): the metal conductor used to connect the lightning receiving device and the grounding device.
3) Grounding device: the sum of the grounding wire and the grounding body. Grounding body refers to resistance reducing agent, ion grounding electrode, flat steel, etc.

"JECSANY" Arrester and Protection Device have stable quality and have third-party IEC test reports, and the products are exported to Southeast Asia, South Africa, South America, the Middle East and other global markets. OEM customization can also be made according to the drawings or samples provided by customers.

48KV 10kA Polymer Surge Arrester

48KV 10kA Polymer Surge Arrester

Model:YH10W-48C1200
M.V. 48KV 10kA Polymer Surge Arrester are used to protect transformers and other equipments in station and distribution systems against the damage by atmospheric (especially lightning effects) and operational conditions. Metal oxides Surge arresters without gaps are designed to prevent probable damages in the case of typical surges in energy systems while it has no negative effect on energy systems in normal operation voltage. This special feature of gapless arresters originating from non-linear characteristics of metal-oxide varistors between voltage and current scales. The non-linear feature is much higher compared to silicon carbide Surge arresters.
