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.

Junray Electrical is a Manufacturer, Supplier and Factory of China's professional ATS Dual Power Automatic Transfer Switch-PC. It was specifically designed to address the issues of weak power splitting and slow switching at the CB level. It adopts a PC-level integrated structure, featuring higher breaking capacity, faster switching, and more reliable operation. It can automatically switch between mains power and backup power to ensure uninterrupted power supply. It is perfectly suitable for scenarios with extremely high requirements for power reliability, such as hospitals and data centers. It supports customization and is the preferred equipment for high-reliability dual power switching.

In the terminal power distribution network, the safety of the lines is often overlooked. Traditional knife switches lack automatic protection functions. Once a line fails, it is highly likely to cause fires or equipment damage. Junray Electrical, as a leading electrical equipment manufacturer in China, introduces the Miniature Circuit Breaker specifically designed for terminal lines. It can cut off overloading and short-circuit currents within milliseconds.

Junray Electrical, as a professional Manufacturer, Supplier and Factory of Molded Case Circuit Breakers in China, focuses on the research and development of low-voltage circuit protection components. This product addresses the pain points of small circuit breakers, such as weak breaking capacity and small capacity, and features dual protection against overload and short circuit. Its breaking capacity and capacity far exceed those of small circuit breakers. It is small in size, easy to install, suitable for low-voltage power distribution scenarios in factories and buildings, and supports customization. It is the preferred equipment for low-voltage circuit protection.

Junray Electrical, as a professional Manufacturer, Supplier and Factory of Box-type Substations in China, focuses on the research and development of large-scale photovoltaic power station integrated prefabricated equipment. The SVG High Voltage Prefabricated Cabin integrates inverters, transformers and other complete photovoltaic equipment. The factory pre-assembles and tests them, and they are ready for connection at the site. They can be deployed in just a few days, eliminating the need to build a power distribution room and saving costs. It is highly reliable with low failure rates, and perfectly suits large-scale photovoltaic power stations and energy storage projects.

Junray Electrical is a Manufacturer, Supplier and Factory specializing in European-style Cable Branch Boxes in China. We adopt a two-way door design and a connecting sleeve busbar structure. The rated current is 630A, with IP33 outdoor protection. The volume is 60% smaller than that of ordinary ring main units. The cable connection is clear, suitable for urban and rural cable networks, and customizable for the number of branches. It is the preferred choice for high-reliability cable branching.
