INQUIRY

Silicone rubber instrument signal cable is suitable for AC rated voltage 300/500V and below, and requires high temperature, low temperature, corrosion resistance, anti-aging and other harsh environments to connect various instruments and meters, computer systems, and signal transmission lines of automation systems.
In order to reduce crosstalk and external interference between circuits,Silicone rubber instrument signal cable needs to be shielded. The shielding materials include tinned or non-tinned copper wire, copper tape, copper-plastic composite tape, aluminum-plastic composite tape, etc., wherein the metal tape is wound and packaged, and the coverage rate is usually not less than 15%, but the specific standard has special The regulations, such as TICW/06, stipulate that the shielding rate of the shielding metal tape should be not less than 25%; the wire should be woven, and the woven coverage should be no less than 80%. If there is a high requirement for anti-interference, the coverage can be no less than 90%. .
The shielding requirements of the cable are adopted according to different occasions: sub-shield (only for the twisted group, each twisted group), the total shielding (the cable only has a total shielding after the cable is cabled), sub-shield + Total shielding (both of the above two structures). According to the higher requirements of the user and the application, the total shielding structure can adopt the composite shielding method, that is, the two-layer shielding is composed of the metal tape wrapping and the wire braiding.
Note: If the Silicone rubber instrument signal cable has a sub-shield structure, the shielding pair should have better insulation performance, and the polyester tape or other non-hygroscopic tape should be wrapped around the sub-shield.
Silicone rubber instrument signal cable belongs to the cable for electrical equipment. The structure and composition of the cable for electrical equipment are the most complicated. According to the special requirements of the operating temperature and working environment, the various materials of the computer cable are various, as follows:

Permissible maximum operating temperature (°C)	Name of insulating material	Sheath Material Name
70	Polyethylene, polyvinyl chloride, thermoplastic polyolefin	Polyethylene and polyvinyl chloride
90	Polyvinyl chloride, crosslinked polyethylene, thermoplastic or thermosetting polyolefins	Polyvinyl chloride, thermoplastic or thermosetting polyolefins
105	Polyvinyl chloride and thermosetting polyolefin materials	Polyvinyl chloride and thermosetting polyolefins
125, 150	Thermosetting Polyolefin Materials	Thermosetting polyolefins
180	silicon rubber	silicon rubber
200	Fluoroplastics	Fluoroplastics
Note 1: Thermosetting polyolefin insulation over 90 C, irradiation is recommended for crosslinking, especially for insulating materials with flame retardant requirements. Note 2: Except for fluoroplastics and silicone rubber, other sheath materials can be used in cables with insulation temperature lower than their own without considering the cost.
