Product Overview

Self Extinguishing Epoxy Resin Cast Dry Transformer 50kVA 10/0.4kV for Safe and Low Fire Hazard Power Distribution 0

This three-phase 50kVA dry-type transformer uses an epoxy resin cast insulation system to combine inherent fire safety with reliable voltage transformation from 10kV down to 0.4kV. By eliminating liquid dielectric, the design removes the leakage and flammability concerns associated with oil-filled units. The result is a compact, self-extinguishing power distribution solution well suited for electrical rooms, substations, and equipment enclosures where personnel safety and property protection are top priorities. Built for continuous duty, the unit integrates easily into new builds and retrofit projects.

Product Highlights
  • Self-Extinguishing Fire Safety: Epoxy resin encapsulated windings are inherently flame retardant and self-extinguishing, drastically lowering fire propagation risk without relying on active suppression systems.
  • Exceptionally Quiet Operation: Optimized core geometry and vibration-damped structural design achieve low sound levels, making the transformer suitable for noise-sensitive electrical installations.
  • High Reliability with Minimal Upkeep: Solid insulation removes the need for liquid sampling or leakage monitoring, cutting lifecycle maintenance compared to conventional liquid-filled alternatives.
  • Compact and Flexible Installation: The space-saving footprint and optional enclosure ratings (IP20/IP23) allow placement close to load centers, inside electrical rooms or compact packaged substations.
  • Robust Environmental Endurance: Epoxy resin casting provides strong resistance to moisture, dust, and chemical contaminants, ensuring stable performance in challenging indoor environments.
Technical Specifications in Detail
Rated Power 50kVA continuous duty (natural air cooling AN, with optional forced air AF for increased overload capability)
Primary Voltage 10kV with standard tapping range (e.g., ±2×2.5% or as specified)
Secondary Voltage 0.4kV three-phase four-wire
Vector Group Dyn11 (standard), other configurations available upon request
Insulation Class Class F or Class H insulation system with temperature rise limit typically designed for Class F (100K) or lower, preserving insulation life
Winding Material High-conductivity copper (standard) or aluminum option, fully encapsulated in epoxy resin under vacuum casting process
Core Construction Grain-oriented silicon steel with step-lap joints to reduce no-load loss and noise
Cooling Method AN (natural air cooling) standard, AF (forced air) optional
Protection Degree IP00 open type for well-ventilated indoor cubicles, optional enclosure upgrades to IP20 or IP23 for direct placement in public accessible areas
Partial Discharge Level ≤ 10pC under rated voltage, verified by routine testing, ensuring long-term insulation integrity
Standards Compliance Designed and tested per IEC 60076-11, EN 50588 or equivalent safety and performance standards
Overload Capacity Engineered to sustain short-term overloads in accordance with IEC dry-type transformer guidelines without compromising insulation life
Application Scenario Solutions: Addressing Concerns in Commercial and Public Power Distribution

Electrical installations in commercial buildings, public venues, and similar gathering spaces face twin concerns: stringent fire safety codes and the need for minimal acoustic disturbance near occupied zones. This epoxy resin cast dry-type transformer directly responds to those conditions through targeted design measures.

Concern: Fire propagation risk in enclosed electrical rooms
Design Solution: The transformer’s self-extinguishing epoxy resin insulation is non-flammable and does not support combustion. No liquid dielectric means no pool fires or flammable vapor release. In the event of an internal arc, the robust cast resin containment limits damage spread, providing essential assurance for below-grade electrical vaults and densely occupied structures.
Concern: Noise disruption in occupied spaces
Design Solution: Low-noise silicon steel core laminations with precision step-lap joints, combined with rigid vibration-damped structural frames, reduce magnetostriction-induced hum. The inherently low sound power level allows the unit to be placed closer to occupied zones without installing additional acoustic enclosures, helping projects meet strict ambient noise criteria.
Concern: Contamination and humidity in semi-controlled environments
Design Solution: The hermetic epoxy resin encapsulation blocks moisture ingress and chemical attack on windings. This eliminates the need for conditioner-controlled atmospheres in many basements and technical rooms, sustaining insulation reliability even during construction-phase exposure or seasonal humidity shifts.
Concern: Space constraints in retrofit and distributed power layouts
Design Solution: Compact footprint and modular enclosure options enable flexible integration into existing switchgear rooms, compact substations, or dedicated transformer cubicles. A close-coupled LV terminal arrangement simplifies cable connections, reducing installation time.
Concern: Maintenance access in continuously operated facilities
Design Solution: With no oil to sample, filter, or replace, the dry-type transformer reduces operational interruptions. Routine checks are limited to visual inspection, ventilation verification, and occasional cleaning, suiting facilities where planned shutdowns are costly or difficult to schedule.

Self Extinguishing Epoxy Resin Cast Dry Transformer 50kVA 10/0.4kV for Safe and Low Fire Hazard Power Distribution 1

Frequently Asked Questions
Q1: Is the epoxy resin insulation truly self-extinguishing, and what fire safety standards does this transformer meet?
A: Yes, the epoxy resin cast winding system is formulated to be flame retardant and self-extinguishing; it will not sustain combustion once an ignition source is removed. The transformer is designed and tested in accordance with fire behavior requirements of IEC 60076-11, offering excellent fire resistance for indoor applications.
Q2: What is the typical sound level for this 50kVA dry-type transformer, and can it be installed near occupied spaces?
A: The standard unit produces low sound pressure levels, typically well below common limits for building services equipment. Exact values are available in the sound level test report. Where additional quietness is required, we can discuss de-rated designs or optional vibration isolation pads.
Q3: What enclosure protection degree do you recommend for installation in a public-accessible electrical room or basement?
A: For general indoor use inside a locked electrical room, an IP00 open type may suffice. However, for areas with potential public traffic, dust, or accidental contact risk, we commonly recommend IP20 or IP23 enclosures to prevent finger contact and provide basic environmental protection.
Q4: How does this epoxy resin cast transformer handle short-term overloads, such as during peak demand in commercial buildings?
A: The transformer is engineered to sustain overloads as defined by IEC dry-type transformer standards without immediate insulation degradation. With optional forced-air cooling (AF) fans, a sustained overload capacity can be provided. We supply specific overload curves upon request to match project loading profiles.
Q5: What kind of technical documentation and factory testing do you provide for EPC project submission?
A: For each transformer we deliver a standard documentation package including routine test reports (turns ratio, winding resistance, dielectric tests, partial discharge measurement, no-load and load loss data), dimensional drawings, and compliance certificates. We can also coordinate special witnessed testing or type test documentation for larger project approvals.
Q6: Can you accommodate special voltage tapping ranges or vector groups for a specific commercial power distribution network?
A: Yes. The standard tapping range is ±2×2.5% on the HV side, but we can adjust tapping or supply non-standard primary voltages. Vector groups other than Dyn11, such as Dyn5 or Yyn0, are available upon request. Please provide the project specification so we can confirm exact production configuration.
