The contact fingers of the composite watchband are made of high-performance and high-quality conductive materials and are manufactured through a special process. It is suitable for the design of the compact electric encounter structure of the switchgear and provides the encounter pressure at the encounter point according to its elastic deformation. The contacts can be made as single point contacts, dual point contacts or inserts containing large contact power transmission to carry the rated power transmission. Dynamic and thermal stable power transmission is widely used in the middle sliding contact of switch cabinet and the contact between moving and static contacts. Positive belt contact refers to a specially formed elastic chain element, which has been used for more than 50 years. It is ideal for high power transmission, high plug life and harsh working conditions. Strip contacts are suitable for various electrical chains of high-voltage electrical appliances and are widely used in high-voltage switches, circuit breakers, bushings and busbars. The contact reed of the strap is made of alloy copper sheet containing good elasticity and conductivity. It is manufactured through a strictly controlled professional process and is suitable for the tight electrical chain of various electrical equipment. The encounter pressure is provided by the elastic deformation of each encounter unit, which can be made to contain a single-point encounter, a double-point encounter or a snap-in encounter with stronger power transmission to carry different requirements for rated power transmission, dynamic and thermally stable power transmission. The power transmission of the ribbon hitting the reed varies from tens of amperes to thousands of amperes. It contains the characteristics of small resistance, simple structure and good reliability, and is widely used in various large power transmission chain occasions.

The construction strip on one side of the contact finger of the composite watchband is stuck into a card slot, the side wall of a card slot is bent to cover the construction strip, and the construction sheet on the other side of the chain bar is stuck into a card slot. The second snap-in groove bends a side wall of the second snap-in groove to cover the building bar. Increasing energy demand and the corresponding capacity expansion of the existing grid require efficient and reliable equipment. Miniaturization of build space and systems requires that the size of equipment and components be reduced without compromising performance. At the same time, energy suppliers and power plants are very concerned about their operating and maintenance costs.


The challenge for the contact fingers of composite watchbands is to provide customers with reliable high-power devices while maintaining economy. The company is committed to improving design solutions and is always looking for space-saving, stable and high-performance touch components. The contact fingers of the composite watchband are made of highly elastic beryllium bronze alloy material, which contains excellent electrical conductivity and high elasticity. It is suitable for various circuit breakers, cable accessories, bus bars and large power transmission industrial chain actuators. Typical applications include ZW20 column vacuum circuit breaker, fuse box, 35KV cable plug, insulating sleeve, large power transmission chain actuator, etc. It can also be used for data transmission, fiber optics, coaxial applications and photovoltaics.


The characteristics of the composite watchband finger: small size, simple structure, no spring compression, multiple electric shocks, large power transmission capacity, high reliability, stable pressure, anti-fatigue, convenient construction, long service life, wear resistance, finger width, Thickness series changes.
