Frequently Asked Questions (FAQ)

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

It is an advanced dry-type power transformer utilizing a three-dimensional triangular core structure. This design optimizes the magnetic circuit distribution, reduces no-load losses, lowers noise levels, and improves overall operational efficiency compared to traditional planar core designs.

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

The primary difference lies in their energy efficiency and loss performance. The SCB13-RL series is designed with advanced materials and optimized structures to offer lower no-load and load losses compared to the SCB11-RL series, meeting higher energy-saving and environmental standards.

What is the standard connection group for these three-dimensional core transformers?

The standard connection group label for the SCB11-RL and SCB13-RL series transformers listed in the technical tables is Dyn11, which is ideal for reducing harmonic distortion in distribution networks.

What rated capacity range do these transformers support?

These three-dimensional triangle core dry-type power transformers support a wide capacity range starting from 30 KVA up to 2500 KVA to accommodate various industrial and commercial distribution requirements.

Are the dimensions and weights shown in the tables absolute?

No, due to continuous product updates and design optimizations, the physical dimensions and overall weights may vary. Customers should always verify and refer to the specific engineering dimensions provided at the time of ordering.
