China Arrester and Protection Device Factory
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.

Arrester Monitor
Model:JCQ-C1
The arrester online monitor (also known as arrester leakage current and action recorder) is an instrument used in conjunction with zinc oxide arresters in high-voltage AC power systems. The instrument is connected in series in the surge arrester grounding circuit. The mA meter in the monitor is used to monitor the leakage current (peak value) through the arrester under the operating voltage, which can determine whether the arrester is damp and whether the components are abnormal; the action counter records the number of overvoltage actions of the arrester.
Arrester Discharge Counter
Model:JSYF8
The discharge counter is the electrical equipment that connected in series under the surge arrester to record the number of operations of the arrester, master the law of lightning activity, continuously improve the reliability of lightning protection of power transmission and distribution equipment, monitor the life of the surge arrester and study the operation of the power system under the action of atmospheric overvoltage.

Station Type Surge Arrester 48KV 10kA with round base
Model:YH10WZ-48C1280
Zinc oxide arrester is the current international advanced overvoltage protector. Because its core component adopts zinc oxide resistance sheet; compared with the traditional silicon carbide arrester, the volt-ampere characteristics of the arrester are improved, and the overvoltage current capacity is improved, thus bringing about fundamental changes in the characteristics of the arrester.
When the arrester is under normal operating voltage, the current flowing through the arrester is only microampere. When subjected to overvoltage, due to the nonlinearity of the zinc oxide resistor, the current flowing through the arrester instantly reaches thousands of amperes. The arrester is in the conducting state, release overvoltage energy, thus effe......

48KV 10kA Polymer Lightning Arrester
Model:YH10W-48C1500
M.V. Polymer Lightning Arresters 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 Lightning 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 lightning arresters.
