Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Medium Voltage Switchgear. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This single-phase isolator switch is intended for high-voltage electrical applications and is offered with customization and OEM production options. The listed technical data covers rated-voltage configurations of 40.5, 72.5, 126, and 252 kV, corresponding to nominal system voltages of 35, 66, 110, and 220 kV.
Listed rated-current selections are 630, 1,250, 1,600, 2,000, 2,500, 3,150, and 4,000 A. Published electrical ratings include a rated short-time withstand current of 25–50 kA for 4 seconds and a rated peak withstand current of 63–125 kA.
Listed minimum insulation distances to ground are 600, 1,000, and 2,000 mm, depending on the selected configuration. The maximum manual operating torque is stated as 200 N-m. Motor-drive operating and control voltage options are listed as AC 220/380 V and DC 110/220 V.
The product information also describes a composite-insulator construction using silicone-rubber shed housing, an epoxy-fiberglass core, and metal end fittings with hot-dip galvanized surfaces for corrosion protection.
However, the supplied data also contains references to porcelain and multiple model or voltage descriptions. Buyers should therefore treat the final construction, model designation, insulator type, and complete rating schedule as order-specific details requiring confirmation.
Before procurement, request the technical drawing and a configuration-specific datasheet.
Confirm the required system voltage, rated voltage, continuous current, short-time and peak withstand ratings, power-frequency and lightning-impulse withstand levels, terminal loads, phase and ground clearances, operating mechanism, control supply, mounting arrangement, and environmental service conditions.
Also confirm which listed standards apply to the exact configuration and obtain the corresponding test and quality documentation. Packaging is described as an export wooden package, while dimensions are stated to be customizable;both should be agreed before shipment.
