Box-type substation and outdoor power distribution equipment
Industries We Serve

Power distribution packages by industry environment.

Different sites require different electrical room layouts, enclosure protection, cabinet combinations and document packages. JSGK matches application conditions with the right product system and RFQ inputs.

Application map

Operating conditions define the product configuration.

The same voltage class can require different cabinet layouts, enclosure ratings and document packages across solar booster stations, industrial plants, rail facilities and coastal outdoor sites.

How selection starts

A clearer route from industry page to quotation.

JSGK supports procurement and engineering teams from operating-condition review to product matching and technical quotation.

  1. 01Define the siteIndoor or outdoor installation, climate exposure, floor plan limits, maintenance access and local document requirements.
  2. 02Confirm electrical dataVoltage class, rated current, short-circuit level, transformer capacity if involved and circuit quantity.
  3. 03Match product familyBox-type substation, prefabricated electrical cabin, switchgear, RMU, LV cabinet or distribution box.
  4. 04Prepare quotation fileShare drawings, technical list and target schedule so the quote can focus on the confirmed scope.
Factory assembly and project delivery preparation
Factory-direct project supportCabinet layouts, inspection records and delivery documents can be prepared according to the confirmed project scope.
Project RFQ

Send the industry, site conditions and electrical parameters.

JSGK can review the application scenario and recommend the relevant product family before model-level quotation.
