Welcome to Jinhua Dika Electrical Equipment Co., Ltd., a dedicated manufacturer with over a decade of expertise in producing high-precision electrical measurement and protection equipment. As a key supplier in the global market, we understand the critical need for reliable monitoring in modern power distribution networks. Our LMZK-10 Current Transformer is engineered specifically for 10kV systems, providing the accuracy and durability that utilities and industrial operators demand for effective energy management, fault detection, and system protection. With a commitment to quality certified by ISO 9001 and other international standards, we deliver products that form the trustworthy foundation of your monitoring infrastructure.
This current transformer is a vital component for safe and efficient power distribution. Its core function is to accurately step down high primary currents to standardized, safe, and measurable secondary levels, enabling precise metering and relay protection. Below are the defining features and technical advantages of the LMZK-10:
- High Precision Measurement: Designed with advanced magnetic core materials and optimized winding techniques to ensure minimal phase and ratio errors, even under varying load conditions. This guarantees accurate data for billing, load profiling, and power quality analysis.
- Robust Construction for Harsh Environments: Featuring a weather-resistant, flame-retardant epoxy resin cast housing, the transformer offers excellent protection against moisture, dust, and chemical corrosion. Its sealed design ensures long-term stability in outdoor substations or indoor switchgear.
- Wide Current Range and Flexibility: Available in a comprehensive range of primary current ratings, from standard 100A to high-capacity 5000A. The through-hole design accommodates various busbar or cable sizes, offering great installation flexibility for different project layouts.
- Enhanced Safety and Reliability: With a high insulation level (LI 75kV, AC 42kV), it provides a reliable safety barrier between the high-voltage primary circuit and the low-voltage secondary instrumentation, protecting personnel and equipment.
- Thermal and Dynamic Stability: Engineered to withstand short-circuit currents and thermal overloads without performance degradation, ensuring continuous operation during network disturbances and contributing to overall grid resilience.

Frequently Asked Questions (FAQ)
Q1: What is the primary application of the LMZK-10 Current Transformer?
A1: It is specifically designed for monitoring, measurement, and protection in 10kV electrical power distribution networks. Common uses include energy metering for utilities, load monitoring in industrial plants, and providing input signals for protective relays.
Q2: Can the LMZK-10 be used for both metering and protection purposes?
A2: Yes, but the required accuracy class differs. For revenue metering, classes like 0.2S or 0.5S are typical. For protection applications (e.g., overcurrent relays), class 5P or 10P is standard. Please specify your intended use so we can configure the correct accuracy class.
Q3: How do I select the correct primary current rating?
A3: The rating should be chosen based on the maximum continuous load current in your circuit, typically 20-30% higher to allow for future load growth. We offer a wide range from 100A to 5000A. Providing your system's maximum load current allows us to recommend the optimal model.
Q4: Is the secondary output 1A or 5A?
A4: Both options are available. The 5A secondary is a traditional standard, while 1A is becoming more common for new installations as it reduces losses in long connecting wires. You can specify your preference when ordering.
Q5: What are the installation requirements for this transformer?
A5: It is designed for straightforward installation. The through-hole design allows a primary conductor (busbar or insulated cable) to pass through the center. It should be mounted on a stable surface in a well-ventilated area, with proper clearance as per local electrical codes. Installation manuals are provided.
Q6: Does it come with any certifications for international markets?
A6: Our manufacturing processes are certified to ISO 9001, ISO 14000, and other management standards. The product itself is designed and tested in accordance with international standards like IEC 60044-1. Specific country certifications (e.g., for a particular market) can be discussed and arranged upon request.
Q7: What is the typical delivery lead time?
A7: For standard models and configurations, we maintain stock for prompt shipment. For large or customized orders, the lead time is typically 4-6 weeks. Exact timing can be confirmed based on your specific order quantity and requirements.
Q8: Do you provide technical support after purchase?
A8: Absolutely. Our technical team provides support for product selection, installation guidance, and application consultation. We are committed to ensuring our products perform successfully in your system.
