Junray Electrical is a professional Manufacturer, Supplier and Factory of CJX2 AC Contactor in China. It was specifically developed to solve the problem of the inability to remotely and automatically control the motor by the knife switch. It can remotely and automatically control the start and stop of the motor as well as the connection and disconnection of the circuit. It can be combined with PLC to achieve automatic control. The opening and closing is reliable and the size is compact. It is suitable for low-voltage motors, residential areas and engineering equipment control. Customization is supported. It is a standard component for low-voltage control.

For the switching of load currents within ring networks, the high-breaking capacity typically found in circuit breakers is unnecessary. The FLN36 Sulfur Hexafluoride Switch—specifically developed by Junray Electrical for use in ring main units (RMUs)—utilizes SF6 arc-extinguishing technology to deliver robust arc-quenching capabilities. Capable of reliably switching load currents, it offers a significantly lower cost compared to standard circuit breakers. It serves as a perfect match for ring main units and cable branch boxes, establishing itself as the standard switch component for ring network systems.

In a 10kV high-voltage power distribution system, the arc-extinguishing capability of circuit breakers directly affects the safety of the power grid. Ordinary switches cannot withstand huge short-circuit currents and are prone to causing serious accidents. Junray Electrical, as a leading electrical equipment manufacturer in China, presents to you the VS1 Vacuum Circuit Breaker, which adopts advanced vacuum arc-extinguishing technology and possesses extremely strong arc-extinguishing capability, capable of easily breaking short-circuit currents as high as 40kA.

Junray Electrical, as a professional Manufacturer, Supplier and Factory of High and Low Voltage Components in China, has developed the Low-Voltage Current Transformer specifically to address the problem that large currents in low voltages cannot be directly compatible with instruments and ordinary ammeters, which are unable to measure large currents. This transformer can convert low-voltage large currents into standard 5A small currents, providing precise signals for instruments, meters and protection devices. It has a smaller size than high-voltage transformers, is easy to install, has a high cost-performance ratio, is suitable for various scenarios such as low-voltage power distribution and distribution boxes, and supports customization. It is a standard essential equipment for low-voltage power distribution.

As a professional manufacturer and supplier of power equipment in China, Junray Electrical, relying on its own factories, presents this high-performance Current Transformer to you. Designed specifically for high-voltage environments, it adopts a fully sealed insulation structure, effectively solving the problem of inability to directly measure and protect high-voltage large currents. Whether in substations or high-voltage power distribution projects, its high-precision measurement and high reliability can ensure the safe and stable operation of the power grid, and it is an indispensable core component in your power system.

High-voltage potentials cannot be measured directly, nor can they be applied directly to protective devices; furthermore, standard instrumentation is incapable of measuring high voltages. Voltage transformers (VTs) are specialized high-voltage conversion components developed specifically for the measurement and protection of high-voltage systems. They transform high voltages—such as a 10 kV input—into standardized low voltages (e.g., 100 V), enabling instruments and protective relays to accurately measure voltage levels and providing the necessary input signals for protection systems. Perfectly suited for high-voltage power distribution networks and substations, voltage transformers constitute a standard, essential component of high-voltage distribution infrastructure.
