As a professional manufacturer of high-voltage electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. is proud to introduce our Centrally Mounted 33KV Gas Insulated Metering Unit. This precision-engineered unit is designed to provide reliable and accurate voltage transformation and metering for demanding high-voltage applications. By integrating advanced SF6 gas insulation technology with a centrally mounted, compact design, we offer a solution that enhances safety, simplifies installation, and ensures long-term measurement stability in substations and industrial power networks.
Our unit addresses the critical need for dependable metering in 33KV systems, converting high primary voltages to standardized secondary outputs of 11KV/110V for protection relays, energy meters, and SCADA systems. With over a decade of experience serving global markets from North America to Southeast Asia, we combine stringent manufacturing controls, evidenced by our ISO 9001 quality management system, with a deep understanding of international electrical standards to deliver products you can trust.
Core Product Features & Technical Advantages:
- Superior Gas Insulation: Utilizing SF6 gas as the insulating medium, the unit offers exceptional dielectric strength and arc-quenching properties. This design significantly reduces the risk of internal flashovers, allows for a more compact footprint compared to air-insulated designs, and is highly resistant to environmental contaminants like dust and moisture.
- Centrally Mounted, Space-Optimized Design: The integrated, centrally mounted configuration consolidates multiple components (Voltage Transformers, Current Transformers, connections) into a single, robust enclosure. This saves valuable space in switchgear panels or substation layouts, reduces cabling complexity, and facilitates easier maintenance access.
- High Accuracy & Stability: Engineered for precision, the metering unit ensures accurate transformation ratios and minimal phase angle errors, which is crucial for correct billing, load management, and protective relay operation. Its design minimizes the influence of external electromagnetic interference.
- Enhanced Safety & Reliability: The sealed, metal-enclosed gas-insulated construction contains any internal arc fault, protecting personnel and adjacent equipment. The system is designed for minimal maintenance and offers high operational reliability even in harsh climatic conditions.
- Flexible Configuration: While supplied as a complete metering unit, the design allows for customization. Options may include different ratio combinations, specific accuracy classes (e.g., 0.2, 0.5), additional protection features, and various mounting arrangements to suit project specifications.

Frequently Asked Questions (FAQ):
-
Q: What is the primary advantage of SF6 gas insulation in this metering unit?
A: SF6 gas provides excellent dielectric strength, allowing for a more compact design than air-insulated units. It also offers superior arc-quenching capabilities and stability against environmental factors, ensuring consistent performance and safety. -
Q: Can this unit be customized for different voltage ratios or accuracy classes?
A: Yes, customization is a key service. We can engineer units with specific primary/secondary voltage ratios and accuracy classes (like 0.2, 0.5, 1.0 for metering) to meet your precise project requirements. -
Q: What does "centrally mounted" mean for installation?
A: It refers to an integrated design where the core components are housed in a single, central enclosure. This simplifies mounting, typically requiring one primary connection point, and makes the unit easier to install and wire compared to separate, dispersed components. -
Q: Is regular maintenance required for the SF6 gas?
A: The unit is hermetically sealed for life. Under normal operating conditions, no regular gas maintenance or topping-up is required. A pressure gauge or density monitor is usually provided for health indication. -
Q: What are the typical applications for this 33KV/11KV-110V metering unit?
A> It is primarily used in 33KV substations, industrial power intake points, and renewable energy plants for revenue metering, feeder protection, synchronizing, and providing standardized voltage signals to control and monitoring systems. -
Q: What certifications does your manufacturing process hold?
A: Our production is governed by a certified ISO 9001 Quality Management System, ensuring consistent quality control. The specific product certifications required (like KEMA, ASTA, etc.) can be arranged based on project needs. -
Q: What is your shipping and delivery capability?
A: We export globally, with major shipment ports including Shanghai, Tianjin, Guangzhou, and Ningbo. Our experience spans North America, Europe, Asia, Africa, and Oceania, ensuring we can handle logistics for your region efficiently. -
