30kVA Power Transmission Transformer, Dry Type, 50Hz, Class H Insulation System
Product Spotlights
As a dedicated manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing robust and reliable electrical solutions for global power infrastructure. Our 30kVA Dry-Type Power Transmission Transformer is engineered for efficiency and durability in demanding applications. Designed with a Class H insulation system and operating at 50Hz, this transformer is a cornerstone for safe and stable power distribution, reflecting our commitment to quality and international standards.
This transformer is built to deliver consistent performance where reliability is non-negotiable. Its dry-type, cast resin construction eliminates fire and environmental hazards associated with liquid-filled units, making it ideal for indoor installations, renewable energy sites, and commercial complexes. We understand the critical need for minimal maintenance and maximum uptime in power transmission networks, and this product is a direct answer to those requirements.
Core Product Features & Technical Advantages:
- Enhanced Safety & Environmental Friendliness: Being dry-type and flame-retardant, it contains no oil, eliminating risks of leakage, fire, or explosion. This makes it perfectly safe for installation in populated buildings, hospitals, schools, and environmentally sensitive areas.
- Superior Class H Insulation System: The insulation can withstand temperatures up to 180°C, providing a high thermal endurance margin. This results in a longer service life, better overload capacity, and reliable operation in high-ambient-temperature environments.
- Low Maintenance & High Reliability: With no liquid to monitor, filter, or replace, maintenance is significantly reduced to simple periodic cleaning and visual inspections. The sealed windings are resistant to moisture and contaminants, ensuring stable performance.
- Excellent Short-Circuit Strength: The robust construction and design provide high mechanical strength to withstand the electromagnetic forces during short-circuit events, protecting downstream equipment.
- Customizable Design: We offer flexibility in primary and secondary voltage ratings (e.g., 11kV/400V, 6.6kV/480V), tap changers, protection enclosures (IP20, IP23), and winding material (copper or aluminum) to match specific grid requirements and project specs.
- Quiet Operation & Efficient Cooling: The design promotes natural air convection (AN cooling), ensuring efficient heat dissipation with low operating noise levels, suitable for noise-sensitive locations.

Frequently Asked Questions (FAQ):
-
What are the main applications for this 30kVA dry-type transformer?
It is widely used in step-down power distribution for commercial buildings, shopping malls, hospitals, data centers, renewable energy systems (solar/wind farm integration), factory power supply, and mining operations where safety and indoor installation are priorities. -
Why choose a Class H insulation system?
Class H insulation offers a higher temperature index (180°C), providing a greater safety margin under overload conditions or in hot climates. This translates to enhanced durability and a longer expected operational lifespan compared to lower insulation classes. -
Can this transformer be used outdoors?
While designed as a dry-type unit, it can be installed outdoors if provided with a suitable protective enclosure (e.g., IP23 or higher rating for weather protection). Please specify your environmental conditions for a customized solution. -
What is the typical delivery time for a customized voltage specification?
Lead time varies based on customization complexity. Standard designs may ship within 4-6 weeks. We recommend contacting our sales team with your specific requirements for an accurate timeline. -
Do you provide technical drawings and installation guidance?
Yes, detailed dimensional drawings, wiring diagrams, and installation manuals are provided with each unit to ensure correct and safe installation. -
What are the advantages of copper windings versus aluminum windings?
Copper windings generally offer better conductivity, higher mechanical strength, and slightly better efficiency, but at a higher cost. Aluminum windings are a cost-effective alternative with adequate performance for many applications. We can advise based on your budget and technical needs. -
Is remote monitoring or smart features available?
Basic temperature monitoring devices (PT100 sensors) are often included. Options for integrated smart monitoring systems with communication protocols (Modbus, etc.) are available upon request for advanced asset management.
