Frequently Asked Questions

What is a three-dimensional triangle core dry-type power transformer?

It is an advanced dry-type power transformer featuring a core configuration where three core limbs are arranged in a three-dimensional triangular layout. This structure ensures a fully balanced three-phase magnetic circuit, reducing no-load losses, noise levels, and magnetic leakage.

What are the primary differences between the SCB11-RL and SCB13-RL series?

The main difference lies in energy efficiency. The SCB13-RL series is designed with lower no-load loss and load loss parameters compared to the SCB11-RL series, meeting stricter environmental and energy-saving standards.

Why is the Dyn11 connection group label commonly utilized?

The Dyn11 connection group configuration helps suppress third-harmonic currents and provides a stronger capability to handle unbalanced loads, making it highly suitable for modern distribution networks with non-linear loads.

Are the dimensions and weights specified in the tables exact?

The values in the technical tables serve as standard references. Due to continuous product upgrades and design optimizations, dimensions and weights may vary. It is recommended to verify the current specifications with the technical team when ordering.

What are the environmental and safety benefits of dry-type transformers?

Dry-type transformers do not use insulating oil, eliminating the risks of oil leaks, fire hazards, and explosions. This makes them ideal for indoor settings, high-rise buildings, underground facilities, and environmentally protected areas.
