This Ac Gapless Metal Oxide Arrester from Wisdom Automatic Equipment Co., Ltd. is a heavy-duty surge protection device designed for medium to high voltage AC systems, rated between 3kV and 500kV. It suppresses lightning impulses and switching overvoltages, safeguarding transformers, switchgear, and transmission lines. The arrester uses a zinc oxide varistor element housed in a polymer or ceramic sleeve, meeting the GB11032-2010 standard for AC electrical equipment arresters.
The device features a gapless design, assembled by stacking non-linear zinc oxide resistors sealed in a high-voltage insulating ceramic sleeve. It operates with high resistance under normal voltage but shifts to low resistance during overvoltage, rapidly diverting impulse current to ground. Key characteristics include a steep wave response, high shock current tolerance, low residual voltage, and no power frequency continuous current. It is equipped with a detachment device to prevent damage under overload conditions.
Typical applications include grid projects and industrial plants, where it is used indoors or outdoors in environments with ambient temperatures from -40°C to 40°C, altitudes up to 2000m, and earthquake intensities of 8 degrees or below. Buyers in electrical infrastructure procurement often source these arresters from China, India, and South Korea. The product is suited for systems with a rated frequency of 48-62Hz and a maximum wind speed tolerance of 35m/s.

Before ordering, verify the arrester’s voltage rating matches your system requirements, as the 3kV to 500kV range covers a broad spectrum. Confirm compliance with your local standards, as GB11032-2010 may need supplementation with regional certifications. Check if the supplier can provide test reports for residual voltage and shock current tolerance, which are critical for performance validation.
Logistics should account for the arrester’s dimensions and weight, as these are not specified but typical for high-voltage devices. Clarify lead times, as custom voltage classes may require additional production time. Discuss Incoterms such as FOB or CIF, and confirm whether the supplier handles export packaging for fragile ceramic components. Payment terms should be negotiated upfront, with L/C or T/T being common for international transactions.
Quality checks should include visual inspection of the ceramic sleeve for cracks or defects and verification of the detachment device’s functionality. Request documentation for the zinc oxide varistor’s non-linear characteristics and the arrester’s steep wave response. For outdoor installations, ensure the housing material meets UV resistance standards typical for polymer or ceramic enclosures in electrical applications.
