Shielded cable refers to the cable with electromagnetic shielding performance with metal wire braid or metal belt wrapped with shielding layer. It is suitable for transformers and similar equipment that need to shield electromagnetic signals. Cable shielding refers to that the outer mesh braid of the cable has been grounded at one end, which can make the external electromagnetic radiation and magnetic field radiation directly enter the ground without interference to the inner wire. It is generally used for lines with high frequency and low signal level, such as cable TV, lead from frequency converter to motor, analog lead, and some interfering transmission lines, such as computer shielded cable, etc. As long as the cable with shielding layer is called shielded cable, power cable and control cable can be added with shielding layer. Computer and instrument cables generally have shielding layers to prevent the interference of external electromagnetic signals
Rail transit cable is a new type of special wire and cable product born with the development of urban transportation. It can be widely used in intercity rail transit, including various types of Intercity Railway (track) lines and intercity trains, i.e. high-speed railway and other power transmission and distribution networks
elevator power transmission and control cable are widely used in large tower crane, stacker, buckle coiler, outdoor elevator for construction, sewage plant and magnet grab. This product has the characteristics of cold resistance, wear resistance, corrosion resistance, softness, oil resistance and halogen-free. Super mechanical load bearing capacity. It has good bending performance, which is 3 times higher than that of ordinary rubber sheathed cable
Drum cable is applicable to the high-voltage flat cable for the connection of stacker reclaimer and transformer on port machinery in stockyard and wharf with AC rated voltage of 6 / 10kV and below. It is also used for crane, crane, bucket wheel and other large machinery with AC rated voltage of 0.6/1kv and below. It has two shapes: drum flat cable and drum round cable
Nuclear power plant cable refers to the raw materials used for the insulation and sheath of nuclear power plant cables, including plastics, rubber and other varieties. The type of cable is determined by the type of cable. There are two classification methods for cables in nuclear power plants: one is divided by function, including measuring cables, communication cables, instrument cables, fire-proof cables (silicon insulated cables), etc; The other is classified according to the safety level. The safety level of cables used in nuclear power plants belongs to ie, and they should have a service life of more than 40 years. The cables of IE nuclear power plants are divided into three safety levels: K1, K2 and K3.
