As a professional manufacturer with a strong export presence, Jinhua Dika Electrical Equipment Co., Ltd. is proud to introduce our WAKAN JDZX11-10G3 35kV Single Phase Voltage Transformer. Engineered for precision and reliability in medium-voltage applications, this 50VA burden indoor transformer is designed to deliver accurate voltage transformation for metering and protection systems. Our commitment to quality, backed by a robust ISO management system, ensures that every unit meets the stringent demands of global power infrastructure.
The JDZX11-10G3 stands out with its advanced toroidal coil construction, which offers superior magnetic performance and reduced losses compared to conventional designs. This results in enhanced accuracy and long-term stability, critical for revenue metering and protective relaying. We understand the need for dependable components in power networks, which is why our transformers are built to perform consistently under the demanding conditions of 35kV systems.
Core Product Features & Technical Advantages:
- Advanced Toroidal Core Design: The unique doughnut-shaped core minimizes magnetic flux leakage, leading to higher accuracy classes (available up to 0.2) and excellent linearity over a wide range of operating conditions.
- Optimized for Indoor Installation: Designed specifically for indoor switchgear, compact substations, and relay panels, featuring a compact footprint and mounting options suitable for confined spaces.
- Robust Insulation System: Utilizes high-quality resin casting or oil-impregnated insulation (depending on specification) to ensure reliable performance and safety at the 35kV voltage level, with strong dielectric strength.
- Low Thermal Losses: The efficient core material and winding design result in lower no-load losses and reduced heat generation, contributing to enhanced efficiency and extended service life.
- High Burden Capability: With a standard burden of 50VA, it can reliably supply multiple instruments (meters, relays, transducers) simultaneously without compromising accuracy.
- Flexible Configuration: Available in various accuracy classes (0.2, 0.5, 1.0) and with optional features like multiple taps or secondary windings to meet specific project requirements.

Frequently Asked Questions (FAQ):
-
Q: What is the primary application of this JDZX11-10G3 voltage transformer?
A: It is primarily used for voltage measurement and protective relaying in 35kV indoor power distribution systems, such as in factory substations, commercial complexes, and renewable energy plant switchgear. -
Q: Can this transformer be used for both 50Hz and 60Hz power systems?
A: The standard unit is designed for 50Hz operation, which is common in many regions. Operation at 60Hz can be accommodated upon request during the ordering process, as the core design may need adjustment. -
Q: What does the "Toroidal Coil" design mean, and what are its benefits?
A: A toroidal coil is wound on a ring-shaped (doughnut) core. Benefits include lower electromagnetic interference (EMI), reduced magnetic leakage, higher efficiency, and a more compact physical size compared to traditional laminated cores. -
Q: Is the 50VA burden rating sufficient for my application?
A: A 50VA burden is a common standard for indoor metering and protection. It can typically supply several devices. If your connected load (meters, relays) exceeds this, please consult us for a unit with a higher burden rating, which is available. -
Q: What accuracy class should I choose?
A: For high-precision revenue metering, Class 0.2 is recommended. For general metering and monitoring, Class 0.5 is suitable. Class 1.0 is often used for protection circuits and auxiliary measurements. -
Q: Does this transformer come with specific international certifications?
A: Our manufacturing processes are governed by a comprehensive ISO 9001 quality management system. Specific product certifications (like IEC, ANSI) for the transformer can be provided based on your project requirements and are subject to confirmation. -
Q: What are the standard secondary voltage outputs?
A: The most common standard outputs are 100V, 110V, and 120V. Other secondary voltage ratings can be customized to match your existing instrumentation. -
Q: What is the typical lead time for an order?
A: Lead times vary based on order quantity and customization. For standard models, we can often facilitate prompt shipment from our major ports like Shanghai, Ningbo, or Tianjin, given our established export operations.
