Wisdom Automatic Equipment Co., Ltd. manufactures outdoor AC high voltage vacuum circuit breakers designed for 10 kV to 35 kV distribution networks. The breakers employ a longitudinal magnetic field arc extinguishing chamber that provides long electric life and reliable interruption. Contacts are made of copper, and the housing combines steel with an insulating composite material that resists ultraviolet radiation and moisture. The unit incorporates a spring‑operated mechanism, resulting in a compact and lightweight design suitable for substation installation.
Standard models conform to IEC and ANSI standards for high‑voltage vacuum switching devices. Typical breaking capacity for this class of equipment ranges from 31 kA to 63 kA, and the insulation is achieved with silicone rubber or epoxy resin composites that are widely accepted for outdoor use. The breakers can be fitted with an isolation switch, three‑phase linkage, and optional arrester strut insulators, matching common substation configurations. Surface discharge prevention and hydrophobic properties are achieved through the composite housing, a standard practice in modern vacuum switchgear.
Primary customers include utility companies, industrial power plants and renewable energy project developers that require dependable fault interruption. The supplier offers the breakers in bulk quantities and advises importers to confirm minimum order volumes, preferred Incoterms and payment schedules before shipment. Because the product is classified as high‑voltage electrical equipment, buyers should verify compliance certificates and request type‑test reports from the manufacturer.

Importers must first confirm that the vacuum circuit breaker complies with the applicable IEC and ANSI standards and obtain the type‑test report and CE or equivalent certification from Wisdom Automatic Equipment. The buyer should also verify the exact voltage class, breaking capacity and any optional accessories such as isolation switches to ensure compatibility with the target substation layout. Because the supplier does not list a declared production capacity, request a capacity statement and lead‑time estimate before finalising the contract.
Shipping of the breakers is usually arranged by sea freight on a palletised basis, with each unit protected by wooden crates and anti‑corrosion packaging. Typical lead times range from several weeks to a few months depending on order size, so the purchaser should agree on a realistic delivery schedule and specify an Incoterm such as FOB Wuxi or CIF destination port. Payment is commonly secured through a confirmed Letter of Credit, but the exact terms should be negotiated with the supplier.
Before acceptance, the equipment should undergo a visual inspection for physical damage and a functional test performed by a qualified technician to verify opening and closing torque. Third‑party inspection agencies can conduct conformity testing against IEC 61850 and verify the dielectric strength of the insulating composite. Required import documents include a commercial invoice, packing list, test certificates, and a material safety data sheet for the composite housing material.
