Product Overview
JLSZV(Y)9-6/10W is an outdoor stainless steel floor-mounted combined transformer with observation windows for 6kV and 10kV medium-voltage distribution systems. It integrates current transformer (CT) and voltage transformer (PT/VT) functions in a robust stainless steel enclosure with double-door design, providing reliable current and voltage signals for high-voltage energy metering with enhanced visibility and accessibility.
This product is suitable for 6kV and 10kV three-phase AC distribution networks. It is commonly used in substations, industrial facilities, and distribution points requiring floor-mounted installation with internal monitoring capability. The stainless steel enclosure with observation windows provides superior protection while allowing visual inspection of internal components without opening doors.

Application Position
JLSZV(Y)9-6/10W is installed at ground level in substations, industrial yards, or distribution points. The stainless steel floor-mounted design with observation windows provides enhanced durability and allows visual monitoring of internal meters and components. The primary terminals connect to the three-phase medium-voltage circuit, while the secondary terminal box supplies voltage and current signals to active energy meters, reactive energy meters, and monitoring instruments.
Main Applications
- 6kV and 10kV outdoor distribution networks requiring floor-mounted metering with visual monitoring
- Substations and industrial facilities requiring stainless steel enclosure with observation capability
- Applications requiring dual wiring configurations (3-phase and 3-phase 4-wire)
- Coastal areas and harsh environments requiring enhanced corrosion protection
- Active and reactive energy measurement for utility revenue billing
- Applications requiring wide current range from 7.5A to 600A
- Projects requiring State Grid standard compliance (GB17201-2006)
Application Case Studies
Application Scenario 1: Substation Yard Metering with Visual Monitoring
Utilities deploy floor-mounted combined transformers in substation yards for revenue billing and load monitoring. The observation windows allow operators to visually inspect internal meters and components without opening doors, reducing maintenance time and improving safety. The stainless steel enclosure provides superior corrosion resistance in outdoor environments.
Application Scenario 2: Industrial Facility with Flexible Wiring
Industrial facilities with 6kV or 10kV incoming supply require accurate energy measurement with flexible wiring options. The JLSZV(Y)9-6/10W supports both 3-phase and 3-phase 4-wire configurations, accommodating different metering requirements. The observation windows enable quick visual verification of meter readings during routine inspections.
