Buy & Import High Voltage Varistor from Guangdong Foshan Kestar Electronic Co., Ltd. - Wholesale Supply

The High Voltage Varistor offered by Guangdong Foshan Kestar Electronic Co., Ltd. is a metal‑oxide surge protection component based on a zinc‑oxide core enriched with bismuth, cobalt, manganese and antimony oxides. The device is designed for use in high‑voltage arresters and can be supplied in typical voltage ratings from 3 kV to 500 kV, as is common for this product class, and is intended to meet IEC 60099‑4 requirements.

The inclusion of the listed additives improves the varistor’s voltage‑clamping characteristics and thermal stability, allowing it to handle lightning impulse and switching surges. In the industry, such MOVs are usually encapsulated in epoxy resin for moisture protection and terminated with lead wires or crimp lugs. Typical leakage current values are around 0.6 mA at the rated voltage, and impulse current capabilities of up to 25 kA are frequently specified for devices in this segment.

Customers such as utility companies, industrial equipment manufacturers and large‑scale construction firms source these varistors for integration into power‑distribution arresters and protective panels. The public listing does not disclose minimum order quantities, pricing or lead‑time details, so interested buyers should contact the supplier to obtain trade terms, packaging options and any available certification documentation.

About Guangdong Foshan Kestar Electronic Co., Ltd. - Varistor Supplier in China

Guangdong Foshan Kestar Electronic Co., Ltd. is located at No.2 Huansheng Road, Pingzhou Industrial Zone, Foshan, Guangdong, China. The supplier is listed with a harbour‑level trust tier, but the platform shows a 0 % response rate and no average response time, indicating limited recent interaction data.

The company’s catalogue lists high‑voltage metal‑oxide varistors as its primary product line. While the description confirms the use of ZnO‑based formulations with specific metal‑oxide additives, it does not provide explicit certification numbers, production capacity or quality‑management system details, so buyers should request test certificates and factory audit reports as part of due diligence.

Metal oxide varistors (MOV) are zinc-oxide-based surge protection components widely used in high voltage electric arresters for power transmission and distribution systems. These devices provide excellent voltage clamping characteristics for lightning impulse and switching surge protection across utility, industrial, and commercial electrical networks. China and South Korea are leading global suppliers of MOV arresters for international trade.

Frequently Asked Questions About High Voltage Varistor from Guangdong Foshan Kestar Electronic Co., Ltd.
The varistor core is zinc‑oxide (ZnO) combined with bismuth, cobalt, manganese and antimony oxides. Ask the supplier for a detailed composition analysis if your design requires specific impurity limits.

Sourcing High Voltage Varistor from Guangdong Foshan Kestar Electronic Co., Ltd. - China Import Guide

Confirm that the varistors carry an up‑to‑date IEC 60099‑4 test certificate and that the material composition matches your project specifications. Request a sample test report for leakage current and impulse rating before committing to a large purchase.

Clarify the preferred Incoterms, typical production lead time and accepted payment methods with Kestar, as the public data does not specify these details. Because the response rate is shown as zero, allow additional time for correspondence and consider using a secure payment mechanism such as a letter of credit.

Plan a third‑party inspection or factory audit to verify the epoxy encapsulation quality, terminal integrity and dimensional tolerances. Ensure that the supplier can provide a packing list, certificate of conformity and any required customs documentation to facilitate smooth import clearance.
