Cold-proof, oil-proof and halogen-free signal cable

Abstract

The invention discloses a cold-proof, oil-proof and halogen-free signal cable which comprises an outer sheath and an outer wrapping layer, wherein the outer wrapping layer is internally provided with a USB (universal serial bus) transmission line and an RGB (red green blue) coaxial transmission line; the USB transmission line comprises a first weaving layer and a first inner wrapping layer; the first inner wrapping layer is internally provided with first signal lines and power lines; the RGB coaxial transmission line comprises a second weaving layer and a second inner wrapping layer; the second inner wrapping layer is internally provided with three second signal lines and power lines; the power lines consist of power line insulating layers and power line conductors; the first signal lines consist of first insulating layers and first conductors; the second signal lines consist of second conductors, inner insulating layers, oblique cladding layers and inner sheaths; the first insulating layers and the power line insulating layers are made of cold-proof, oil-proof, antiflaming and halogen-free materials; the inner sheaths are made of cold-proof and oil-proof thermoplastic materials; and the outer sheath is made of an oil-proof, halogen-free, antiflaming and low-temperature-resistant XLPE (cross linked polyethylene) material. The cable has high-antiflaming and low-smoke effects, can transmit power and signals, and is good in physical property, corrosion-resistant, and low-temperature-resistant.

Description

technical field [0001] The invention relates to a cable, in particular to a cold-resistant, oil-resistant and halogen-free signal cable. Background technique [0002] In the cold north, the temperature at night is at least minus 40°C, which makes it difficult for many equipment to work in such an environment, especially for oil extraction and well digging. Sometimes the wires are damaged and cause downtime, and the wires cannot withstand the cold or oil, which delays the progress of the project and causes huge losses to the country. Contents of the invention [0003] In order to solve the above problems, the present invention provides a cold-resistant, oil-resistant and halogen-free signal cable. The cold-resistant, oil-resistant and halogen-free signal cable of the present invention has the characteristics of high flame retardancy and low smoke effect, and can transmit signals while transmitting power. It has the characteristics of good physical properties, corrosion res...

Problems solved by technology

[0002] In the cold north, the temperature at night is at least minus 40°C, which makes it difficult for many equipment to work in such an environment, especially for oil extraction and well digging. Sometimes the wires are damaged and cause downtime. The wires either cannot withstand the cold or are not resistant to oil, which delays the progress of the project and causes huge losses to the country.
