Product Description & Features

Our cast resin dry-type transformers (10kV, 50kVA-3150kVA) are engineered for indoor, low-maintenance power distribution. These units are ideal for data centers, hospitals, high-rise buildings, and industrial plants requiring oil-free, fire-safe equipment.

  • Insulation Class: Class F (155℃) high-temperature resistance.
  • Protection Grade: IP20 protection with built-in PT100 temperature sensors.
  • High Efficiency: Copper winding for low loss and optimal performance.
  • Safety Standards: Flame-retardant epoxy resin encapsulation (IEC 60076-11 compliant).
  • Low Noise: Advanced design ensures noise levels ≤55dB.

Frequently Asked Questions
Q1: What standards does your low voltage switchgear comply with?
A: Our switchgear is designed and manufactured in full compliance with the international IEC 61439 series of standards (specifically IEC 61439-1 & -2). We also hold complete Type Test Certification (TTA) and meet relevant national standards such as GB7251.1.
Q2: What is the meaning of "Form 4B" separation?
A: Form 4B is a classification per IEC 61439 that specifies the highest degree of internal separation. It ensures complete isolation between the busbars, functional units, and outgoing terminal compartments, enhancing safety and allowing for safer maintenance.
Q3: What is the advantage of a withdrawable circuit breaker design?
A: A withdrawable design allows for the circuit breaker to be easily disconnected and isolated without de-energizing the entire panel. This enables safe and rapid maintenance or replacement, minimizing downtime for critical power systems.
Q4: What is the short-circuit withstand rating (Icw) of your panels?
A: Our standard panels are rated for a short-time withstand current (Icw) of 50kA for 1 second. This ensures the assembly can withstand thermal and electromagnetic stresses during a fault. Higher ratings can be engineered for specific projects.
Q5: What is the typical delivery lead time for a custom switchgear project?
A: For standard configurations, the lead time is typically 4-6 weeks. For fully customized projects involving complex engineering, the lead time can range from 8 to 12 weeks depending on technical specifications.
Q6: What maintenance is required for cast resin dry-type transformers?
A: These transformers are virtually maintenance-free. Periodic visual inspections and checking of temperature monitoring systems are recommended to ensure optimal performance in indoor environments.
