As a professional manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in producing high-quality electrical components for global power systems. Our 35kV Indoor P.T Cast Resin Potential Transformer model WAKAN JDZX11-10G3 is engineered for precision and durability in demanding indoor high-voltage environments. This transformer provides accurate voltage measurement and reliable protection, ensuring the safety and stability of your electrical infrastructure. With a focus on innovation and stringent quality control, we deliver products that meet the exacting standards of international markets, backed by our commitment to excellence and customer satisfaction.
This potential transformer is a critical component for metering and protective relaying in substations and industrial facilities. Its advanced design and robust construction offer significant advantages over conventional models.
Key Features and Technical Advantages:
- Superior Insulation with Cast Resin: The entire core and coil assembly is encapsulated in high-grade epoxy resin. This process eliminates air pockets, providing exceptional dielectric strength, moisture resistance, and protection against environmental contaminants. It results in a maintenance-free, non-flammable, and highly reliable unit.
- Advanced Toroidal Coil Design: Unlike traditional rectangular coils, the toroidal (ring-shaped) coil offers a symmetrical magnetic field with minimal magnetic flux leakage. This design enhances measurement accuracy, reduces losses, and improves overall efficiency and thermal performance.
- Precision Voltage Transformation: Designed for a rated primary voltage of 35kV, it accurately steps down the high voltage to standardized low-voltage levels (typically 110V or 100/√3 V) suitable for meters and relays. This ensures precise energy metering and fast, reliable operation of protective devices.
- Compact and Lightweight Construction: The cast resin technology allows for a more compact and lighter design compared to oil-immersed transformers. This simplifies handling, reduces installation space requirements, and lowers structural support costs.
- Wide Frequency Compatibility: Rated for both 50Hz and 60Hz operation, this transformer is perfectly suited for global applications, providing flexibility for projects in different power grid standards.
- Enhanced Safety: Being a dry-type, resin-insulated transformer, it poses no risk of oil leakage or fire hazards associated with liquid-filled units. This makes it an ideal choice for indoor installations where safety is paramount.

Frequently Asked Questions (FAQ):
-
Q: What is the primary application of this 35kV Cast Resin Potential Transformer?
A: Its main application is for precise voltage measurement and providing a safe, isolated signal for protective relays and energy metering equipment within indoor high-voltage switchgear and substations operating at 35kV. -
Q: How does the cast resin insulation benefit the transformer compared to oil insulation?
A: Cast resin insulation offers several benefits: it is maintenance-free (no oil checks or changes), non-flammable, environmentally safe (no risk of leaks), provides excellent resistance to moisture and pollution, and allows for a more compact design. -
Q: Why is the toroidal coil design considered advantageous?
A: The toroidal coil design creates a uniform magnetic field with very low external magnetic interference (stray flux). This leads to higher measurement accuracy, better performance under unbalanced loads, reduced electromagnetic interference (EMI) on nearby equipment, and improved thermal characteristics. -
Q: Is this transformer suitable for both 50Hz and 60Hz power systems?
A: Yes, the model WAKAN JDZX11-10G3 is explicitly designed and rated for operation at both 50Hz and 60Hz frequencies, making it a versatile choice for international projects. -
Q: What accuracy classes are available for this potential transformer?
A: Accuracy classes such as 0.2, 0.5, and 1.0 are typically available. The specific class depends on the application requirements for metering or protection. Please consult with us for the exact options. -
Q: Can this transformer be used outdoors?
A: No, this specific model is designed for indoor installation. The cast resin provides excellent protection, but for direct outdoor exposure to sunlight, rain, and extreme temperatures, a transformer with additional UV-stabilized and weatherproof housing would be required. -
Q: What are the mounting and connection options?
A: It is designed for fixed mounting within switchgear panels or on dedicated frames. Connection terminals are typically provided for both primary (high voltage) and secondary (low voltage) circuits. Detailed mechanical drawings and connection diagrams are provided upon request. -
Q: Does your company provide custom specifications for voltage transformers?
A: As a manufacturer, we have the capability to discuss modifications or custom designs based on specific project requirements, such as different voltage ratios, special accuracy needs, or unique mounting configurations. Please contact our technical sales team with your specifications.
