Power cable
Product Introduction:
Power cable is used for transmission and distribution of high power electricity in the main line of the power system, including 1-500kV and above all kinds of voltage grade, all kinds of insulation power cable.
Product performance:
The most basic performance of power cable is the electrical performance, because the power cable works under high voltage, so the electrical performance requirements are in many aspects, but also very strict, in the design of cable must be accurate calculation of the electrical performance, and according to this as the basis for the selection of materials and structures. Electrical performance mainly includes: dc resistance and AC resistance of conductor, insulation resistance of insulation layer, cable capacitance, inductance, dielectric loss and breakdown strength. In addition, there are heat resistance, mechanical properties, as well as different types of cable with special performance. These properties of power cable not only depend on the cable structure, the performance of raw materials used, and cable manufacturing process and quality are closely related.
Electrical equipment wire and cable
Product Introduction:
The electrical energy is transmitted directly from the last switching device to various electrical equipment and appliances for connecting wires and cables; Internal connection and installation lines of various electrical equipment; And wires and cables used in signal, measurement and control systems are collectively referred to as wires and cables for electrical equipment.
Product performance:
There are many kinds of electrical equipment cables, complicated names, various insulation and sheath materials used, and different performance indexes.
Special cable
Product introduction
Special cable is the cable with special purpose, can be used in specific occasions, such as high temperature resistance, acid and alkali resistance, termite resistance, as well as in ships, aircraft, nuclear power plants and other occasions used wire and cable. In terms of classification, it does not belong to the same classification method as power, control, computer cables and other categories, that is, the above listed cables also include special cables. General special cables need to develop enterprise internal control standards. Special cable is a series of products with unique performance and special structure. Compared with ordinary wire and cable with large quantity and wide range, it has the characteristics of higher technical content, stricter use conditions, smaller batch size and higher added value. New materials, new structures, new processes and new design calculations are often used.
Product performance
Special cable because of its use of special environment, special requirements for its product performance, therefore, some special cable production is very difficult, very professional, there must be special production equipment, high requirements for insulation and sheath materials, production process control is very strict.
Optical cable, data cable
Product introduction
Optical fiber cable is manufactured to meet the requirements of optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers in a covering sheath as transmission medium and can be used individually or in groups.
Data cable: with the rapid development of optical communication technology, optical fiber has been widely used in the backbone network and inter-office relay lines of China's wired communication network, and it has become an inevitable trend for optical fiber to enter the access network. However, the cost of cable laying is too high, the cost of joint and the cost of terminal opto-electric conversion is too high. Therefore, before the popularization of optical fiber, the user line of access network will still be dominated by metal cable.
Product performance
Optical cable is mainly composed of optical fiber (as thin as hair glass wire) and plastic protection sleeve and plastic skin, optical cable without gold, silver, copper, aluminum and other metals, generally no recycling value. Optical cable is a kind of communication line with a certain number of optical fibers composed of cable core in a certain way, covered with a sheath, and some covered with an outer sheath, to realize the transmission of optical signals. That is, a cable made of optical fibers (optical transmission carriers) through a certain process. The basic structure of optical cable is generally composed of cable core, reinforcing steel wire, filler and sheath, and waterproof layer, buffer layer, insulating metal wire and other components according to the need.
Data cables mainly include all-plastic cable, coaxial cable and data cable. Among them, data cable is the ideal broadband access network transmission media, it has the advantages of low manufacturing cost, simple structure, good scalability, easy to upgrade the network, mainly used in the building integrated wiring, residential computer integrated wiring and so on.
applications
Optical cable can be used for long-distance trunk lines, urban relay, offshore and transocean undersea communications, as well as LAN, private network and other cable transmission line backbone, and began to develop to the area of urban user loop distribution network, for fiber to home, broadband integrated services digital network to provide transmission lines.
Data cables can be used in a variety of applications, such as data centers, switches, servers, security monitoring, locomotives, aerospace, wind power, tow chains, robotics and other highly flexible applications.
