2025 Power Kazakhstan Exhbition— HEYI contributes to safe electricity use

 

From October 21st to October 23rd, 2025, Wenzhou HEYI Electric will meet you in Almaty.

 

 

Wenzhou HEYI Electric was established in 2012, specializing in the research, design, manufacture and sale of current transformers, current sensors, digital meters, shunts, current transmitters and related accessories, which are widely used in the smart grid industry, covering power distribution, power saving, protection and metering of electricity and power systems. (The focus is on continuous improvement, innovation and high-performance, cost-effective solutions).

We have a strong R&D and quality control team, constantly innovating new solutions, additions and extensions, pursuing not only meeting but exceeding market demands and providing the best solutions for our customers.

 

 

 

HEYI ‘s mission is to provide reliable, accurate and customized current transformer solutions

 

HEYI ‘s vision is to become a global leading manufacturer of split current transformers and energy solutions provider

 

HEYI’s values: Be passionate about work and provide customers with high-quality personalized and considerate services

 

HEYI sincerely provides you with high-quality products and efficient services, and is willing to start cooperation with you as soon as possible.

 

 

 

 

HEYI Electric’s two core products

 

Split core current transformer KCT

 

KCT series split type current transformers are designed with compact size to fit in tight spaces, and the calmp-on design allows for easy installation around cables without breaking the circuit. Built-in precision resistors on the CT secondary winding provide a low safety voltage output.

 

 

Current measurement, monitoring and protection of electrical circuits and equipment.

 

Current and power measurement for electric motors, lighting, air compressors, heating and ventilation systems, air conditioning equipment and automated control systems.

 

Current, power and energy monitoring devices.

 

Relay protection device.

 

 

 

 

 B-type residual current sensor

HYCA is a residual current sensor for leakage protection developed specifically for electric vehicle charging, providing full current sensitivity. Charging electric vehicles using a standard wall socket or wall charger box requires a DC fault current protection device to avoid electric shock. The installed type A residual current circuit breaker (RCCB) cannot identify and deactivate DC fault current.

 

 

 

 

Advantage

Small size, small footprint, can be integrated into compact IC-CPDs Avoids dangerous situations caused by DC fault currents

Protects type A RCCB from saturation：

Save expensive Type B RCCD

Volume optimization

Low-cost AC/DC current sensitivity

 

Protects type A RCCB from saturation：

Self-monitoring and testing capabilities

Robust mechanical design suitable for IC-CPD

 

 

 

 

Product Features

Fault current detection in accordance with IEC 62752 or UL 2231 standards

Frequency range DC up to 2 KHz

Load current up to 80 Arms (single phase) or 3 x 32 Arms (three phase)

Switching output 6 mA DC and 30 mA AC (according to IEC 62752)

Integrated self-monitoring and testing functions

 

 

Measurement resolution is 0.2 mA

Variants with through-opening or integrated main conductor

Differential current range 0~300 mA

Robust mechanical design suitable for IC-CPD environmental requirements (e.g. drop test)

Widely used in harsh electronic environments (e.g., resistance to external magnetic fields)

 

 

Sensors can trigger automatic shutdown in the event of dangerous electrical faults (DC and AC) according to IEC 62752 or UL2231 standards.

 

 

 

 

 

Sincerely invite you to visit us and seek common development

 

We have many excellent products waiting for you. We sincerely invite global customers and industry partners to come to the Kazakhstan Power Energy Exhibition PowerExpo . Let us work together for the development of global clean energy.
