Our Service Policy
Welcome to the transformer and cables service area of NPC Electric. We focus on providing customers with comprehensive, high-quality transformer-related services. With a professional technical team, rich industry experience and advanced equipment, we are committed to meeting the various needs of different customers for transformers in the power system and ensuring the stable and efficient transmission of electricity.
Pre-sales Service
According to customer needs, we provide professional transformer configuration suggestions, including transformer capacity, model, cooling method, etc. We organize internal experts to review the design plan to ensure the scientificity, rationality and feasibility of the plan. We provide a variety of quotation options for different plans and configurations, so that customers can make appropriate decisions based on their own budgets.
Technical Support
Expert technical assistance is available at every stage of the project lifecycle—from initial planning and procurement to installation, commissioning, and ongoing operation. Manufacturers typically maintain dedicated support teams composed of experienced engineers and technicians who work closely with clients to ensure seamless integration and optimal performance of their products.
Quality Assurance
Each transformer undergoes multiple rounds of rigorous performance tests, including voltage withstand tests, short-circuit tests, temperature rise tests, etc., to ensure the quality and precision of each transformer so that it can operate efficiently and stably under specific working environments and load conditions.
Repair and Maintenance
Regular repair and maintenance are essential to extend the life of your transformer. We provide regular inspections, troubleshooting, emergency repairs and technical support services to help customers keep their transformers in optimal operating condition. We have a team of experienced technicians who can quickly locate and resolve equipment problems.
Training Services
We provide on-site training (at the customer's site or company training center) and online training (through live webcasts and video courses). We cover the daily maintenance points of transformers (such as cleaning, lubrication, tightening, etc.), common fault diagnosis and treatment, safety precautions, etc.
After-sales service
We provide technical support such as 24-hour hotline, online customer service, remote assistance software (which can view equipment operation data in real time and guide operation). In the event of a transformer failure, our technical team is always on call.

We had obtained ISO9001, ISO14001, OHSAS18001 certificates and KEMA, CESI test report for our large transformers.
FAQ From Customers
-
What is a Transformer?A transformer is an electrical device used to change the voltage of alternating current (AC). It works on the principle of electromagnetic induction, converting high-voltage current into low-voltage current or low-voltage current into high-voltage current. Transformers are widely used in power transmission, distribution systems, and various electronic devices.
-
What are the main uses of a transformer?The main use of a transformer is voltage conversion. Transformers are used in power transmission systems to help transfer electricity from power plants to consumers. In addition, transformers are also used in electronic devices such as chargers, televisions, power adapters, etc., to adjust the voltage to meet the requirements of different devices.
-
Do you have UL listed?Yes, our transformer has UL listed. We have exported to America many pad mounted transformer,substation transformer and HV.
-
What are the main properties of the insulation material of the power cable?(1) High breakdown strength; (2) Low dielectric loss; (3) Very high insulation resistance; (4) Excellent discharge resistance; (5) It has certain flexibility and mechanical strength; (6) Long-term insulation performance is stable.
-
What are the regulations for cable protection tubes?(1) When the cable needs to be laid through a protective pipe, the inner diameter of the pipe should not be less than 1.5 times the outer diameter of the cable, and the inner diameter of the concrete pipe, clay pipe, asbestos, and cement pipe should not be less than 100mm; (2) The bending radius of the cable tube should meet the requirements of the bending radius of the cable inserted; (3) Each pipe should not exceed three elbows at most, and there should be no more than two right-angle bends.
