3.high temperature resistant cable
High-temperature-resistant wire and cable is a cable that can properly transmit signals or electrical energy at high temperatures.
High-temperature resistant cable can also be normal transmission of electricity and signals in high-temperature environments, widely used in metallurgy, petrochemical, aviation and other fields. This cable generally uses high temperature and heat-resistant materials as insulation materials, such as acrylic, PTFE, etc..
Cable structure parameters

1,AC rated voltage: U0/U 450/750KV.
2,Maximum working temperature: polyperfluoroethylene propylene (F46) insulation does not exceed 200℃, soluble polytetrafluoroethylene (PFA) insulation does not exceed 260℃.
3, the minimum ambient temperature: PVC sheath: fixed laying -40 ℃, non-fixed laying -15 ℃, fluorine plastic and silicone rubber sheath: fixed laying -60 ℃, non-fixed laying -20 ℃.
4, cable installation and laying temperature should not be less than 0 ℃ (fluorine plastic, silicone rubber and composite sheath cable not less than -25 ℃).
5, the permissible bending radius of the cable: non-armored cable minimum 6 times the outer diameter of the cable, copper tape shielded or steel tape armored cable minimum 12 times the outer diameter of the cable, fluorine plastic insulation and sheath cable minimum 8 times the outer diameter of the cable.
4.fiber optic cable
Optical fiber cable is a kind of cable with optical fiber as the transmission medium, which has the advantages of high-speed transmission, large bandwidth, anti-interference and so on. Fiber optic cable is widely used in communications, Internet, broadcasting and other fields, and plays an important role in modern society.
Basic Structure
Fiber optic cable is composed of several parts such as cable core, reinforcing steel wire, filler and sheath, etc. In addition, there are waterproof layer, buffer layer, insulated metal conductor and other components according to the need.
Fiber optic cable consists of 3 parts: reinforcing core and core, sheath and outer jacket. Cable core structure has a single-core type and multi-core type two kinds: single-core type has a full type and tube bundle type two kinds; multi-core type has a band and unit type two kinds. The outer sheath has metal armor and non-armor two kinds.
Types
- According to the transmission performance, distance and use of different, fiber optic cable can be divided into user cable, telephone cable, long-distance cable and submarine cable.
- According to the different types of optical fibers used within the cable, the cable can be divided into single-mode fiber optic cable and multi-mode fiber optic cable.
- According to the number of fiber optic cores in the cable, the cable can be divided into single-core optical fiber cable, dual-core optical fiber cable and so on.
- According to the different methods of configuration of the reinforcement, fiber optic cable can be divided into the center to strengthen the components of the cable, dispersed reinforcement components of the cable, sheath reinforcement components of the cable and the comprehensive outer layer of the cable.
- According to the transmission conductor, media condition, optical fiber cable can be divided into metal-free optical fiber cable, ordinary optical fiber cable, integrated optical fiber cable (mainly used for railroad special network communication lines).
- According to different laying methods, fiber optic cables can be divided into pipe cables, directly buried cables, aerial cables and underwater cables.
- According to the structure of different ways, the cable can be divided into flat structure cable, stranded cable, skeleton cable, armored cable and high-density user cable.
5.anti-theft cable
Anti-theft cable is a vibration alarm, power failure alarm and other functions of the cable, widely used in the need to protect important equipment or valuable materials, such as jewelry auction houses, museums and so on.
In short, special cables have their own different characteristics and areas of application, in the cable selection and application occasions need to be selected according to specific requirements!
