Meta Description
LBAJI delivers customized 22kV cast resin dry-type transformer solutions for Vietnam industrial park indoor power distribution projects. We provide one-stop services including professional solution design, precision manufacturing, strict factory testing, export-standard packaging, on-site installation and commissioning, ensuring safe, stable, low-maintenance and energy-efficient power supply for industrial manufacturing operations.
1. Project Overview
Modern industrial parks in Vietnam have high standards for power supply safety, stability and environmental adaptability, especially for indoor electrical equipment deployed in intensive factory buildings. This Vietnam industrial park project focuses on supporting continuous and stable power consumption for precision manufacturing workshops, production equipment and public supporting electrical facilities.
Considering the indoor closed installation environment, dense equipment layout, and strict local industrial fire safety regulations, traditional oil-immersed transformers with fire hazards and high maintenance costs were completely excluded. Finally, LBAJI’s high-performance 22kV/0.4kV cast resin dry-type transformer was selected as the core power distribution equipment to build a safe, reliable and compact medium-voltage power supply system for the park.
2. Project Challenge
The industrial park’s indoor power distribution scenario put forward strict comprehensive requirements for transformer performance, installation and later operation, bringing multiple construction challenges:
Indoor Closed Installation: Limited space in the indoor power distribution room requires compact equipment structure and no oil leakage pollution risk, adapting to dense indoor layout
High Fire Safety Standard: Industrial manufacturing scenarios have high fire prevention requirements, needing flame-retardant, self-extinguishing and explosion-proof transformer performance to eliminate hidden fire dangers
Low Maintenance Operation: The industrial park covers a large area with numerous electrical equipment, requiring transformers with stable performance and minimal daily maintenance to reduce later operation costs
Ultra-Stable Power Supply: Precision manufacturing equipment is sensitive to voltage fluctuation, requiring low loss, low noise and anti-interference power output to avoid production shutdown and product loss caused by power instability
Space-Saving Layout: The power distribution room has fixed construction specifications, requiring optimized equipment structure to match compact electrical room layout and save infrastructure transformation costs
3. LBAJI Solution
Combined with Vietnam’s national power grid standards, industrial park application scenarios and client’s personalized demands, LBAJI tailored a 22kV medium-voltage cast resin dry-type transformer integrated power distribution solution, targeting all pain points of the project. Different from ordinary dry-type transformers, our customized solution adopts upgraded vacuum casting process and optimized electromagnetic structure design, perfectly adapting to long-term indoor continuous operation in high-temperature and high-humidity environments in Vietnam.
The overall solution integrates transformer main equipment, high and low voltage connecting accessories, intelligent temperature control system and safety protection devices, realizing integrated delivery and one-stop installation and commissioning, effectively shortening the project construction cycle and ensuring the matching degree of the whole power distribution system.
