As a professional manufacturer with ISO9001 certified quality management, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing reliable and precise electrical measurement solutions. Our 35KV Indoor Voltage Transformer with Epoxy Resin Cast Insulation represents our commitment to combining advanced insulation technology with robust construction for demanding indoor substation environments. Designed for accuracy and long-term stability, this transformer ensures safe and efficient voltage measurement and protection in your power systems.
This voltage transformer is engineered to deliver exceptional performance. The core of its reliability lies in the epoxy resin cast insulation, which provides superior dielectric strength, excellent resistance to environmental contaminants, and outstanding mechanical protection for the internal windings. This construction method effectively prevents partial discharges and enhances the product's service life, making it a dependable choice for critical metering and relay protection circuits.
Key Features & Technical Advantages:
- Superior Insulation Integrity: The use of high-grade epoxy resin in a vacuum casting process creates a solid, void-free insulation barrier. This results in high partial discharge inception voltage, excellent thermal conductivity, and resistance to moisture, dust, and chemicals commonly found in indoor electrical rooms.
- Compact & Space-Saving Design: Compared to traditional oil-filled or air-insulated units, the epoxy cast design allows for a more compact form factor. This is particularly advantageous for indoor switchgear and compact substations where space is at a premium.
- Maintenance-Free Operation: The sealed, solid insulation system is inherently maintenance-free. There is no need for periodic oil testing or drying out procedures, significantly reducing lifecycle costs and operational downtime.
- High Accuracy & Stability: Precision-engineered magnetic cores and windings ensure consistent accuracy over a wide range of operating conditions and temperatures. This stability is crucial for revenue metering and sensitive protection schemes.
- Robust Mechanical Strength: The epoxy resin casting provides excellent mechanical support, protecting the internal components from vibration, short-circuit forces, and accidental impact during handling or installation.
- Enhanced Safety: The solid insulation eliminates the risk of oil leaks or fires associated with liquid-filled transformers, contributing to a safer working environment for personnel and equipment.

Frequently Asked Questions (FAQ):
-
What is the primary advantage of epoxy resin cast insulation over other types?
Epoxy resin cast insulation offers a sealed, solid dielectric system. It provides excellent resistance to environmental factors like humidity and pollution, superior mechanical strength to withstand short-circuit forces, and is completely maintenance-free, unlike oil-insulated units which may require monitoring and servicing. -
Can this voltage transformer be used for both metering and protection applications?
Yes, it can. The transformer is available in different accuracy classes. Higher accuracy classes like 0.2 or 0.5 are typically used for metering, while protection classes (e.g., 3P, 6P) are designed for relay protection circuits, ensuring reliable operation during fault conditions. -
What does the warranty cover, and what is its typical duration?
Our warranty covers defects in materials and workmanship under normal use and service conditions. The specific duration and terms are provided with the commercial offer and are designed to give customers confidence in the product's reliability. -
Is this product suitable for installation in areas with high humidity?
Yes, the epoxy resin cast insulation provides an excellent moisture barrier, making it well-suited for indoor environments where humidity control might be a concern. The solid encapsulation prevents moisture ingress into the active parts. -
Do you offer custom rated voltages or ratios?
Absolutely. As a manufacturer, we can customize the primary and secondary voltage ratings, accuracy classes, and terminal arrangements to meet the specific requirements of your project. Please provide your detailed specifications for a tailored quotation. -
What are the standard delivery ports and lead time?
We ship from major Chinese ports including Shanghai, Tianjin, Guangzhou, and Ningbo. Lead time depends on order quantity and specification complexity; standard products typically have a shorter delivery cycle. Specific timelines will be confirmed upon order placement. -
How should this indoor voltage transformer be installed and maintained?
Installation involves secure mounting via its flange or bracket and proper connection of primary and secondary terminals following local electrical codes. Maintenance is minimal due to the solid insulation; periodic visual inspection for cleanliness and checking connection tightness is generally sufficient. -
What international standards does this product conform to?
Our voltage transformers are designed and tested in accordance with widely recognized international standards such as the IEC 61869 series for instrument transformers. Compliance with other regional standards can be discussed based on project needs.
