China High Voltage Ceramic Insulator Manufacturer, Supplier, Factory

FKN12-12D series air-blast Ioad break switch and FKRN12-12D series air-blast load break switch-fuse combination apparatus are new series switchgear applies to three-phase electric distribution system of rated 12kV, acting as protecting and control apparatus for transformers, cable and overhead wiring. These series are especially applicable in rural, urban terminal substation and prefabricated substations, as well as ring network power supply. FKN12-12D can break and make Ioad current and over-current. FKRN12-12D can break and make over-current load current and short-circuit current(Iimited current fuse). This product is featured with impact structure aesthetic appearance. reliable interlock and high insulating level. In the spring storage operation mechanism, ON/OFF speed is free from the influence of the manpower. For the arc-extinguish, electric arc-extinguish inside the insulating cover, the free gas occurs at sparking do not cause descend of insulating level between phases and phase to earth. The insulation cover clapboard separates electrified part thus boost protection grade of ring main unit. The copper-tungsten contact and main contact brings along reliable conductivity and long life. This product achieves sound fame due to easy maintenance and operation as well as reliable performance. It is in compliance with IEC62271-105.

The Switchgear Side Cover Strip is a vital component designed to enhance the protection and aesthetic appeal of electrical switchgear assemblies. Made from high-quality, durable materials, this strip serves as a protective barrier, shielding the internal components of the switchgear from dust, moisture, and other environmental contaminants. Its design ensures a secure fit along the edges of the switchgear, preventing accidental contact with live parts and contributing to overall safety.

interlocking mechanism for switchgear Switchgear Interlocking Mechanism - Product Details and Applications The Switchgear Interlocking Mechanism is a critical safety and operational component designed to ensure the secure and coordinated operation of electrical switchgear. This mechanism prevents inadvertent or unauthorized operation of switches, breakers, and other electrical equipment by establishing a series of interlocking conditions. Typically installed within the switchgear panel, the interlocking mechanism is activated during specific operational sequences to prevent the opening or closing of certain parts unless predefined conditions are met.

The Switchgear Drawer Bottom Board is a critical component designed to provide structural stability and support to the entire switchgear assembly. Made from high-grade, corrosion-resistant materials, such as galvanized steel or stainless steel, the bottom plate ensures durability and long service life even in demanding industrial environments. Its precision-engineered construction allows for secure mounting and alignment of internal components, facilitating ease of installation and maintenance.

The Indoor High-Voltage Switchgear Ground Switch is a critical safety device designed for use in high-voltage electrical systems, ensuring safe grounding and isolation of equipment during maintenance and servicing. Suitable for voltage ranges from 12kV to 40.5kV, it provides exceptional resistance to short-circuit conditions and delivers reliable mechanical operation. Its compact and efficient design simplifies installation and ensures ease of use, making it an ideal choice for integration in high-voltage switchgear and substations. This grounding switch adheres to international standards, guaranteeing safe and stable performance in complex electrical networks.
