Jinhua Dika Electrical Equipment Co., Ltd., a trusted ISO9001-certified manufacturer with over $1 million in annual exports, specializes in engineered solutions for global power infrastructure. Our Low Noise Indoor Power Transformers (6/10/12kV) are precision-built for the demanding environments of modern urban substations, where space constraints and noise regulations are critical. Engineered with advanced magnetic core technology and optimized cooling, these transformers deliver exceptional reliability while minimizing acoustic footprint – a vital advantage for densely populated areas.
Core Product Advantages & Technical Specifications:
- Advanced Acoustic Engineering: Utilizes stepped core construction, vibration-dampening mounts, and optimized flux density to achieve noise levels typically ≤55dB(A) at 1 meter, significantly below conventional units.
- Urban Environment Optimized: Compact footprint and robust indoor design withstand temperature fluctuations and pollution levels common in city settings, reducing land acquisition costs and environmental impact.
- Enhanced Efficiency & Longevity: Constructed with high-grade, low-loss grain-oriented silicon steel cores and electrolytic copper windings for minimal no-load and load losses, translating to lower operating costs and extended service life.
- Robust Safety & Protection: Features include pressure relief devices, Buchholz relays (gas detection), temperature indicators (WTI/OTI), and hermetically sealed tanks to prevent moisture ingress, ensuring operational safety.
- Flexible Configuration: Available with multiple voltage taps (±2x2.5% or ±5%), various cable box arrangements (front/rear/side), and optional accessories (surge arresters, protective cages).

Frequently Asked Questions (FAQ):
-
Q: What is the typical lead time for these transformers?
A: Standard units typically have a lead time of 8-12 weeks. Larger or customized units may require 12-16 weeks. Expedited options are available upon request. -
Q: Can these transformers be used in retrofitting older urban substations?
A: Yes, their compact design and flexible terminal configurations (cable box/bushing) make them well-suited for retrofitting projects where space is limited and noise reduction is critical. -
Q: How is the low noise performance achieved?
A> We employ a combination of stepped core lamination to reduce magnetostriction, specialized core clamping to minimize vibration, optimized flux density, and vibration-dampening materials in the tank construction and mounting. -
Q: What maintenance is required?
A: These are low-maintenance units. Routine checks include oil level and condition monitoring (DGA recommended annually), visual inspections for leaks, and cleaning of radiators/cooling surfaces. Full maintenance schedules are provided. -
Q: Are bushings or cable boxes included?
A> Both options are available. Standard configurations include cable boxes suitable for XLPE or PILC cables. Bushings (porcelain or composite) can be specified based on your switchgear connection needs. -
Q: Do you offer different oil types?
A> Standard units use high-quality mineral oil. Biodegradable ester oil options are available upon request for enhanced fire safety or environmental sensitivity. -
Q: Can you provide transformers compliant with specific regional standards (e.g., ANSI, IEC, etc.)?
A> Absolutely. While our standard design follows IEC 60076, we have extensive experience manufacturing transformers to meet ANSI C57.12.00, IEEE C57.12.90, and other regional specifications. Please specify your requirements. -
Q: What warranty do you provide?
A> We offer a standard 12-month warranty from the date of commissioning or 18 months from shipment, whichever comes first, covering manufacturing defects. Extended warranty options are available.
