Vacuum Interrupters TJ-1.14/1000B
The Vacuum Interrupters TJ-1.14/1000B are compact medium‑voltage protection devices designed for 1.14 kV, 1000 A applications. They feature a ceramic shell housing and contacts made of copper‑tungsten carbide (CuWC). The unit employs one‑shut technology, providing high insulation and low stop‑flow during interruption. According to the supplier, the design delivers strong blowout performance and a long service life.
Ceramic shells are standard in vacuum interrupters because of their dielectric strength and resistance to contamination. CuWC contacts are typical for high‑current units, offering low contact resistance and wear resistance. In the industry, comparable interrupters are rated up to 1.5 kV and 1500 A, with typical insulation resistance above 10⁹ Ω and dielectric strength around 30 kV cm⁻¹. Standard mechanical endurance is specified for at least 10⁵ making‑and‑breaking cycles under a temperature range of - 40 °C to +85 °C.
The interrupters are commonly sourced by electrical equipment manufacturers and switchgear factories for OEM assemblies. Buyers should confirm minimum order quantities, packaging details such as anti‑static wooden crates, and the preferred Incoterm with the supplier. Payment terms and lead times are not listed and must be negotiated directly.

Sourcing Vacuum Interrupters TJ-1.14/1000B from Kunshan Guoli Electronic Technology Co. Ltd. - China Import Guide
When placing an order for the TJ‑1.14/1000B, the importer should first verify that the part number, voltage rating, and current rating match the project specifications. It is advisable to request the supplier’s material test report confirming the CuWC contact composition and the ceramic shell’s dielectric strength. Buyers should also ask for a certification copy such as IEC 62271‑100 conformity or any factory acceptance test results. Confirming these documents reduces the risk of receiving a non‑matching component.
Typical shipment of the interrupters is arranged on an FOB basis from the port of Shanghai, but the exact departure port should be confirmed with the supplier. Lead‑time information is not disclosed in the listing, so the buyer must ask for an estimated production and dispatch schedule. Payment terms are usually negotiated as a Letter of Credit at sight or a 30‑day documentary collection, but these should be agreed in the contract. Verify the Incoterm and any freight insurance requirements before finalising the purchase.
Importers are encouraged to arrange a pre‑shipment inspection that includes visual examination of the ceramic housing and dimensional verification against the typical size of 120 mm × 80 mm. An electrical test to measure insulation resistance and dielectric strength should be performed according to IEC 62271‑100 guidelines. Request the supplier’s test certificates and a full inspection report, and consider retaining a third‑party laboratory for independent verification if the order volume is large. Proper documentation will streamline customs clearance and warranty claims.
