CSA C227.4 Transformers in Canada
Three-phase, pad-mounted distribution transformers with separable insulated high-voltage connectors — supplied to the CAN/CSA-C227.4 standard.
Purcee Industrial Power supplies CSA C227.4 pad-mounted transformers across Canada. As the exclusive Canadian distributor of Yawei transformers, we help utilities, developers and EPCs source three-phase, pad-mounted distribution transformers built to meet CAN/CSA-C227.4 for underground distribution systems — configured and shipped from our Foothills, Alberta head office.
If your project specifies CSA C227.4, send us your voltage and kVA and we'll confirm a compliant pad-mounted configuration with the right loop- or radial-feed arrangement and separable insulated high-voltage connectors.
Overview
What is the CSA C227.4 standard?
CSA C227.4, “Three-phase, pad-mounted distribution transformers with separable insulated high-voltage connectors” (current edition C227.4:21), specifies the requirements for three-phase, 60 Hz, liquid-filled pad-mounted distribution transformers used by electric utilities on underground distribution systems.
The standard applies to units rated 3000 kVA or below, up to 34.5 kV system nominal voltage, with separable insulated high-voltage connectors, suitable for outdoor pad mounting without additional protective enclosures. It covers voltage and kVA ratings, mechanical characteristics and test procedures, plus performance requirements including energy efficiency (per CAN/CSA-C802.1), temperature rise, loading capability, audible sound level and radio influence voltage (RIV).
Specifying to CSA C227.4 gives Canadian utilities a recognised baseline for pad-mounted distribution transformers. Confirm your exact voltage class, kVA and connector requirements when you request a quote.
