Product features

    Gw5-40.5/72.5/126 series of isolation switches are produced and sold by our company. They mainly optimize the heating of the conductive circuit, the reliability of providing electricity, the stagnation of the transmission part, the anti-corrosion of the bearing seat, the anti-corrosion of the surface of the isolation switch, and the simplification of on-site installation and debugging workload. They have the following characteristics:

◆ gw5-40.5/72.5/126 series isolation switch conductive rod adopts angular aluminum structure to increase the conductive heat dissipation area and improve the conductive reliability;

◆Gw5-40.5/72.5/126 series disconnecting switch adopts new contact and external pressure contact structure. Compared with the original structure, the contact and contact have large surface area, good heat dissipation ability, eliminate the skin effect, and good self-cleaning and wear resistance. The depth of the contact finger inserted into the contact head of the structure is deep, which greatly improves the conductive reliability.

◆Gw5-40.5/72.5/126 series isolation switches adopt advanced silver plating technology, which greatly increases the adhesion of the coating, and adopts appropriate contact pressure to ensure the long-term work of the silver coating does not fall off;

◆Gw5-40.5/72.5/126 series disconnecting switch connection socket and connection terminal adopt fixed soft connection flow; The upper and lower ends of the terminals are insulated bushing to ensure reliable flow and flexible rotation. The terminal and outgoing column are of integral structure, which increases the strength and reduces a possible hot spot at the same time.

◆ gw5-40.5/72.5/126 series isolation switch adopts fully sealed structure bearing housing, upper and lower double seal, to prevent rain, sand erosion of rotating bearing, bearing surface filled with sufficient amount of working temperature range of +130℃ ~ -60℃ wide temperature grease, to ensure hot climate and cold areas do not occur lubrication failure;

◆Gw5-40.5/72.5/126 series disconnecting switch drive shaft pin is made of stainless steel, the transmission link is made of hot-dip galvanized or stainless steel joint bearing, strong anti-corrosion ability, low rotational resistance, small clearance, reliable transmission, can effectively avoid rust death of rotating shaft, ensure flexible rotation;

◆Gw5-40.5/72.5/126 series isolation switch ground knife adopts one-step action structure, ground contact adopts self-power structure, the structure is simple and beautiful, the operation force is small, the action is reliable;

◆ Gw5-40.5/72.5/126 series steel components of isolation switch are treated by hot-dip galvanizing process; Silver or tin plating on the surface of copper parts;

◆ the main ground knife mechanism and the body of the vertical transmission rod connected by splint and hoop connection mode, cancel the field welding and drilling, and is very convenient for users to install, debug, disassemble and maintenance;

◆ the main knife with CJTKB improved electric mechanism, the ground knife with CS17A improved human body, using stainless steel or aluminum alloy body, beautiful appearance, strong anti-corrosion ability, with good waterproof, dustproof performance. Secondary components are domestic famous or joint venture quality products. It has interlocking unit, which can satisfy various interlocking functions at the same time.

◆ adopt high quality and high strength strut insulator with stable performance and reliable quality, require the porcelain bottle to show sand at sintering point and adopt waterproof structure, which can meet the safety factor of 2.75 times of mechanical load.
