GNEE Electric Supplies 1500kVA Oil-Immersed Transformer For Pakistan Industrial Project

GNEE Electric, a professional power distribution equipment manufacturer with full industrial chain vertical integration capability, has recently provided a complete set of customized power distribution solutions for a leading chemical industrial project in Pakistan.

 

The core supply includes a 1500kVA oil-immersed outdoor transformer and matching HT & LT switchgear panels – all designed and manufactured in strict compliance with IEC international standards, tailored to Pakistan's high-temperature operating environment and long-term full-load production demand.

 

 

Driven by the expansion of Pakistan's chemical, manufacturing and industrial parks, demand for high-reliability distribution transformers has grown rapidly. Restricted by the local high-temperature climate (summer temperatures often exceeding 40°C) and long-term full-load operation, industrial users frequently face seal aging oil leakage, excessive winding temperature rise and over-temperature tripping – leading to unplanned shutdowns and high maintenance costs.

 

The client, a well-known chemical enterprise in Pakistan, launched procurement for its new production line. Core requirements focused on IEC standard compliance, stable operation under high-temperature conditions, and one-stop supply of transformer and switchgear to reduce multi-supplier coordination costs and parameter mismatch risks.

Targeting high-temperature adaptation and long-term reliability, GNEE applied its full-lifecycle quality control system across four dimensions:

 

1. Anti-Leakage Manufacturing

Tank welding: Integral bending + automatic welding; 100% penetrant testing on critical welds

Leak test: 24-hour vacuum positive-pressure test at ≥0.05 MPa before delivery – eliminates pinholes and blowholes

Seals: FKM (Viton) gaskets standard on all flanges – stable at 200°C, preventing NBR hardening/cracking under high oil temperatures

Corrosion protection: Shot blasting + epoxy zinc-rich primer + polyurethane topcoat (Grade ≥C3) for outdoor installation

 

2. Overheating Prevention

Windings: 100% pure copper + high-permeability grain-oriented silicon steel core – losses strictly meet IEC 60076 limits

Cooling: ONAN system with enlarged radiator area ensures top oil temperature rise ≤60K at 40°C ambient; reserves space for future ONAF upgrade

Monitoring: PT100 sensors for real-time oil temperature and winding hotspot monitoring, with high-temperature alarm and over-temperature trip protection

 

3. One-Stop Switchgear Matching

Integrated supply of transformer + HT + LT switchgear – all parameters pre-matched at design stage

Eliminates multi-supplier adaptation issues, shortens on-site commissioning, simplifies unified after-sales management

 

4. Full Compliance Documentation

Complete IEC type test reports, factory test reports and technical datasheets

Fully supports client's local grid acceptance and project approval

 

 

GNEE Electric has prioritized production to meet the client's project schedule. All equipment is packed in standard export sea-worthy packaging and will be delivered within the agreed lead time.

 

After-sales commitment:

• 1-year product warranty
• Remote installation guidance, commissioning consultation and O&M training
• 24-hour response to fault consultations
• Regular oil quality testing and maintenance recommendations to extend equipment service life

 

 

This Pakistan 1500kVA transformer project marks another important practice of GNEE Electric's localized solution strategy for the South Asian market. In recent years, GNEE has been deeply engaged in the global industrial distribution transformer market, developing targeted product solutions for different regional climate characteristics, grid standards and industrial demands.

 

Leveraging its full industrial chain manufacturing advantages – from high-permeability grain-oriented silicon steel to finished transformers – GNEE continues to focus on power equipment reliability and energy efficiency, providing industrial clients in Pakistan and worldwide with high-quality, low-failure transformer products and full-cycle power distribution solutions.
