Product descriptions from the supplier
Description
Product Introduction
This 100 kVA transformer, is a step-down unit with a rated capacity of 100 kVA, converting from a primary voltage of 11 kV to a secondary voltage of 0.38 kV. The primary side is equipped with a ±2×2.5% no-load tap changer for flexible voltage adjustment.
Designed using cutting-edge technology and built with premium materials and components, this distribution transformer delivers exceptional reliability and an extended operational lifespan. Every unit undergoes a full suite of acceptance tests before delivery, and we have maintained a 10-year track record of zero faults. Our oil-immersed power transformers are engineered to comply with IEC, ANSI, and other leading international standards.
Features
- Integrated Self-Protection Design ：Integrates fuses, temperature protection, and overload protection devices, eliminating the need for additional external protection equipment. It can quickly cut off the circuit in case of faults, significantly improving the safety of power grid operation.
- High Adaptability for Pole-Mounted Installation ：Adopts a lightweight and compact structural design, suitable for pole-mounted installation in overhead line scenarios. It is easy to install, occupies little space, and is especially ideal for the rapid deployment of distribution networks.
- Optimized for 11kV Distribution Scenarios：Specifically designed for 11kV medium-voltage distribution scenarios, equipped with a ±2×2.5% no-load tap changer to flexibly adjust the output voltage and adapt to complex grid voltage fluctuations.
- High Reliability & Long Service Life：Made of high-quality insulating materials with a fully sealed structure, it offers excellent moisture-proof, dust-proof, and corrosion-resistant performance. It adapts to harsh outdoor environments and enables long-term stable operation.
- Compliant with International Standards：Strictly designed and manufactured in accordance with international authoritative standards such as IEC and ANSI. Each unit undergoes full-performance testing before delivery, ensuring global applicability and compliance in distribution scenarios.

Transformer leads
- Transformer leads have three requirements: (electrical performance), (mechanical strength) and (temperature rise requirements).
- The power transformer leads are (bare copper wire), (paper-wrapped round copper wire), (bare bus bar), (cable) and (copper tube), etc.
- Our factory adopts lead connection method (brazing) (gas welding) (cold pressure welding) (mechanical connection).
Oil Tank:
The basic functions of transformer oil tank can be summarized as protection of oil tank and holding oil, installation skeleton of external components and heat dissipation.
