Infrastructure & Municipal Industry
- Airports, highways, metros, bridges, tunnels
- City lighting systems, streetlight projects
- Smart city developments

At NPC Electric, we provide a range of high-quality products for the successful implementation of Infrastructure, including airports, highways, metros, bridges, tunnels. Our expertise also extends to Municipal Industry, including City lighting systems, streetlight projects.
In this series of important municipal construction, cables and transformers play an indispensable role in ensuring the reliability and safety of power supply. The following are some key products we supply for these projects:
Medium voltage underground cables-33kV transformers are often key equipment in power conversion and distribution between high voltage and medium voltage power networks.
Low-voltage underground cables-Reasonable selection of the cross-section of underground low voltage cables can provide a basis for improving the quality of power supply.
Pad Mounted transformers 2500kVA-Suitable for utilities, universities, hospitals, industrial or commercial energy distribution systems, etc.
33kV Power Transformer-To be applied to the power distribution system, it can convert the 33 kV voltage to meet the voltage requirements of different users.

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.
