JLDZ6-10W Outdoor Single-phase Epoxy Resin Casting Combined Transformer 10kV

This is a 10 kV outdoor single-phase combined instrument transformer that integrates current and voltage functions in one epoxy-resin-cast unit, feeding metering and protection circuits in distribution switchgear and substations. Its dry epoxy resin insulation and cast construction suit outdoor service, with a pollution class IV creepage profile for exposed locations.

The unit delivers accuracy classes 0.2 and 0.5 with a rated burden of 0.2 VA at 50/60 Hz, so secondary cabling and meter loads must be matched to that window. It follows GB/T 17201, and type and routine test reports are available [On Request]. Typical deployment is on outdoor distribution lines, pole-mounted or in box substations.

Earth the secondary at one point and bond the case; never open-circuit the current secondary or short-circuit the voltage secondary while energized. Verify polarity and ratio before energization. Custom ratios, accuracy classes and documentation packages are quoted on request, with lead time confirmed at inquiry. ⚠️ Safety: Follow the nameplate terminal diagram and ground the secondary winding at one point.
