10kV PT

Product Description

The 10kV PT manufactured by DAHU ELECTRIC is an essential component in indoor switch cabinets, playing a crucial role in modern electrical systems. It not only measures voltage but also performs important tasks such as electrical energy monitoring and ensuring the smooth operation of protective relays in both single-phase and three-phase AC systems.

In addition to its functional capabilities, the10 kV PT from DAHU ELECTRIC is known for its commitment to quality and innovation. It incorporates advanced features, undergoes rigorous testing, and complies with industry standards, ensuring reliable performance.

Product Introduction

Cold-rolled silicon steel sheet :10 kV PT often uses cold-rolled silicon steel sheet as its core due to its excellent magnetic properties. These materials exhibit high permeability and low core loss, making them ideal for efficient energy transfer. They have lower hysteresis loops and magnetization losses compared to other options, resulting in less energy waste and lower power consumption.

Epoxy resin: Epoxy resin has excellent dielectric properties and mechanical strength, is the first choice of 10 kV PT insulation material. Epoxy castings provide reliable insulation that protects internal components from electrical breakdown and environmental factors.

Copper : Copper conductors are typically used for windings in 10 kV PT. These materials offer high electrical conductivity and mechanical durability, enabling efficient transmission of current signals while withstanding operational stresses.

Material (Epoxy Resin ): 10 kV PT use enclosures made of epoxy resin, which has excellent insulation properties and can prevent current or voltage crossing for safe circuit operation. It is also resistant to high temperatures and corrosion, and has good sealing performance for waterproof and moisture-proof capabilities. Epoxy transformers are lighter and easier to install and maintain compared to oil-immersed transformers.

Product Superiority

Our product plating of screws and bottom plate reaches 8um/min, which is more moisture-proof and rust-proof. The gloss is better.
