Product Functions
◆Accurately transforms high voltage to a standardized, measurable low voltage signal for metering and protection devices.
◆Provides essential electrical isolation between the high-voltage primary circuit and secondary control circuits for safety.
◆Facilitates reliable system protection through mutual inductance characteristics matched for short-circuit current conditions.
Applicable Environment
◇Primarily installed within Ring Main Units (RMUs) or compact ring network cabinet switchgear.
◇Ideal for indoor applications where space optimization is critical and environmental ◇protection is needed.
◇Suitable for electrical distribution networks requiring robust, space-saving voltage sensing components.
Product Highlights
◆Compact & Space-Saving: The fully sealed construction significantly reduces the overall volume required within the switchgear cabinet.
◆Enhanced Durability: Resin insulation combined with a sealed structure provides outstanding resistance to pollution, dust, and moisture.
◆Optimized Design: Features double oxygen winding and is engineered for mutual inductance short-circuit current matching, ensuring stability during fault conditions.
◆RMU-Specialized: Specifically developed to meet the stringent size and performance requirements of modern ring main units.
Installation Instructions
◇This transformer is designed for fixed installation within the designated compartment of a ring network cabinet or RMU.
◇Ensure the cabinet environment is clean and dry prior to installation to maintain the unit's sealed integrity.
◇Securely connect the primary terminals to the high-voltage busbars and the secondary terminals to the corresponding measurement or protection circuits as per wiring diagrams.
◇When ordering, users must specify the required model (JDZ18-6, JDZ18-10R) and quantity. ◇Provide all main technical parameters (voltage ratios, accuracy class, etc.) as per the manufacturer's specification table.
◇For any non-standard requirements (special ratios, dimensions), directly negotiate customization details with the manufacturer before ordering.
