The novelty, flexibility and originality of the busbar device appliance. It indicates the vitality of this skill and its broad market prospects. This is the real reason why we pay attention to it.
First of all, this kind of small electrical equipment is a novel concept, using the "non-hole lap technology" (the author's right to call it so), and the electrical equipment is directly installed on the busbar to form a power distribution or control loop. The representative creations are busbar device fuses and fuse load blocking switches.
Secondly, WOHNER Electrical Systems has developed a multi-standard modular bus system, and its bus system is diversified in modulus and standard, and the additional value is serialized. The modulus of the bus system is 40mm, 60ram, 100/185mm; The bus cross-section forms are rectangular, double "T" (i.e., "H" shape) and three "T" shapes (i.e., "state" shapes); The standard of the bus bar can be three-wire, four-wire or five-wire, or even seven-wire, of course, it should be determined according to the need. Additional voltage of the bus system: 690V; Additional currents are: 630A/800A (rectangular), 1600A (double "T") and 2500A (triple "T"). The short-time withstand current of the bus system reaches 50kA (1s), and the peak withstand current reaches 117kA (three-wire)/120kA (four-wire).
WOHNER Electrical Systems has also developed a series of busbar adapters and a variety of busbar terminal blocks using the "Holeless Lap Technique" – universal busbar adapters, wire nose bolt couplings and three-phase combination terminal blocks.
The busbar adapter clamp is suitable for both rectangular busbars and double "T" type or triple "T" type busbars; There are direct hard connections and soft connections; There are straight splint types with hard joints, and there are 90 types. Angular lap type; There are straight and 900 corner joints: the cross-section of the wire can be connected to the rectangular copper and aluminum bar, and the circular or even fan-section cable can be connected. Wire nose bolt adapter clamps are suitable for connecting cables with "O" or "U" type crimp terminals. The three-phase combined terminal block can be connected with a protective cover, or without a protective stripe, it can be connected to a rectangular copper and aluminum bar, or it can be connected to a cable or a soft flat copper foil busbar. The additional current of the busbar adapter clamp varies from 630 to 2500A; The additional current of the general-purpose busbar adapter clamp is 1 80-800A; The additional current of the wire nose bolt coupling clamp is 63-250 # 4 The additional voltage of the three-phase combined terminal board is 690V, and the additional current is 63-1250A.
Thirdly, another creation of WOHNER Electric's "non-porous articulation skills" is the busbar adapter. The bus adapter is a transition part of the electrical equipment directly installed on the bus system. It can be used to install air circuit breakers, contactors and control appliances and other components of major companies in the world such as Germany Siemens, AEG, Klckner-Moeller, United States GE, France Schneider, Switzerland ABB, Japan Mitsubishi and other major companies in the world on the busbar. There are several types of bus adapters: the Eques Easycontroller and the Eques Easyconnectorer with integral insulated panels. The additional voltage is 690V; There are four standards for each type by additional ammeter: 25, 32, 63 and 80A. They can be carried without a standard rail or with 1 or 2 standard rails. There is also a universal bus adapter with an additional voltage of 690V; There are 160, 200 and 630A_ standards for additional currents. The universal busbar adapter is suitable for the direct installation of electrical components of larger standards.
Eventually, w6HNER Electrical Systems has developed a series of other products, such as a series of universal fuses for electrical cabinets, fuse blocking switches, generalized and serialized insulating components and protective parts.

Difference Between Busbar and Cable in Power System – Wiener
Busbar refers to a product made of copper (copper bar) and aluminum materials with high conductivity to transmit electric energy and have the ability to gather and distribute electricity. The main conductor used by the power station or substation to transmit electrical energy. Through it, the electrical energy output from generators, transformers or rectifiers is delivered to individual users.
