Its unique composition includes circuit breakers, disconnectors, earthing switches, current transformers, voltage transformers, and surge arresters, all enclosed in a metal housing filled with sulfur hexafluoride (SF6) gas, a highly effective insulating medium.

72.5KV 4000A Horizontal or Vertical knee-type disconnector features a compact design, modern aesthetic, and sleek appearance. It is reliable, efficient, and economical, with a space-saving vertical contact system that adapts to varying heights. The terminal block and conductive rod are crafted from high-quality aluminum alloy and aluminum alloy sections, offering excellent strength, durability, and resistance to corrosion.

The New Armored Removable AC Metal-Enclosed Switchgear, a testament to advanced switchgear technology, the 35kv 1200 amp 1250a mv switchgear is specifically crafted for three-phase AC power systems with a rated voltage of 35kV. It accommodates rated currents ranging from 630a to 3150a, and operates at a frequency of 50Hz. This cutting-edge equipment not only facilitates the efficient transfer and distribution of electric energy but also offers robust control, protection, and monitoring capabilities for electrical circuits, ensuring optimal performance and reliability.

The outdoor oil-immersed transformers at 10kV, 20kV, and 35kV levels have an advanced design with improved performance characteristics. They feature a unique structure with three core columns arranged in an equilateral triangle configuration. These gaps within the magnetic circuit, along with a core column loss, help reduce noise levels and ensure better balance of the transformer components. Additionally, these transformers effectively minimize the presence of the third harmonic component. They are suitable for various applications, including urban and rural areas, industrial and mining power grids, and are particularly well-suited for combination transformers and pre-installed substations.

The 12KV 1600A Medium Voltage Mv Electrical Switchgear KYN28-12(Z) AC metal armored switchgear is designed for three-phase AC power systems with a rated voltage of 12kV and a rated frequency of 50Hz. It serves as a reliable and efficient solution for receiving, distributing, controlling, protecting, and monitoring electrical energy in various applications..

Product Overview This circuit breaker is a low-voltage protection device designed for AC 50/60Hz power distribution networks with rated voltages up to 400V and currents up to 63A, suitable for industrial, commercial, and residential electrical systems. It integrates comprehensive safety and operational safeguards: High-sensitivity Residual Current Detection (RCD) technology provides indirect contact protection to mitigate electric shock risks, while overload long-time delay protection and short-circuit instantaneous tripping ensure precise fault current interruption, preventing equipment damage and fire hazards. The device also supports infrequent circuit switching and intermittent motor start-stop operations, meeting flexible control demands in standard power distribution scenarios. Key Features & Applications Featuring a modular compact design compatible with global power standards, it is ideal for data centers, manufacturing facilities, and building distribution panels, particularly in environments requiring high power continuity and safety. The thermomagnetic dual-protection mechanism guarantees stable overload response and rapid short-circuit breaking, enhanced by 50/60Hz frequency compatibility for robust system reliability. With a durable construction and rail-mounted quick installation, it serves as a reliable solution for modern smart grids, balancing safety, efficiency, and ease of maintenance.
