Product Overview

This three phase, six compositions combined CT&VT, consists of three semi-insulation VTs of Y-Y wiring and three CTs series connected with phase A,B,C. Secondary leads in junction box is easy for wiring and testing. Use epoxy resin insulation stunt structure for outdoor installation. Applicable for highest voltage for equipments no more than 24kV for metering/measuring measurement in power system.

Key Features

• Fully Sealed Structure & Weather-resistant Materials：With a fully sealed design and weather-resistant materials, it achieves IP65 protection rating, resisting salt fog, dust, UV radiation, and other harsh environmental factors to ensure long-term outdoor operational stability.
•  Integrated Combined Design：Integrates voltage transformer with protection components (e.g., fuses) as a single unit, reducing equipment footprint, simplifying substation layout, and lowering installation & maintenance costs.
• Wide Temperature Adaptability：Operates stably within -40℃ to +70℃, using low-temperature tough epoxy resin and high-temperature resistant insulation materials to prevent insulation aging caused by temperature fluctuations in extreme environments.
• High Insulation Reliability：The insulation system passes 12kV/42kV/75kV withstand voltage tests with partial discharge ≤5pC. Built-in overvoltage protection devices effectively prevent damage from switching overvoltage and lightning impulse.
• Strong Anti-fouling Capability：With external insulation creepage distance ≥31mm/kV and anti-fouling silicone coating, it suits Class Ⅲ and above pollution areas, reducing the risk of flashover accidents and maintenance frequency.
