Abstract

The utility model discloses an environment-friendly type flexible high-temperature resistant cable used for aviation and aerospace. The cable comprises two parallel conductive wire cores, and the conductive wire cores comprise seven strands of conductors, wherein six strands of surrounding conductors distribute around one strand of central conductor. The six strands of surrounding conductors are respectively formed by stranding 25 wires. The one strand of central conductor is formed by stranding 38 conducting thin-wires. Insulating layers respectively wrap outside the two parallel conductive wire cores to form cable cores. A belting layer formed by a highly flame retardant low smoke zero halogen belting wraps outside the cable cores. Rock wool is filled between the belting layer and the cable cores. A sheath layer is extruded outside the belting layer. The conductive wire cores of the cable are formed by a plurality of conductors. Low smoke zero halogen flame retardant polyolefin -150 is used in insulation and sheath. The rock wool material which is very hard to burn is filled. The highly flame retardant low smoke zero halogen belting is used to wrap. The cable can be widely applied in the field of aviation and aerospace, and has excellent characteristics of high-temperature resistance, environmental friendly, flexible, etc.

Description

The soft high temperature-resistant cable of a kind of environment-friendly type Aero-Space

Technical field:

The utility model relates to the space flight cable, relates in particular to the soft high temperature-resistant cable of a kind of environment-friendly type Aero-Space.

Background technology:

Along with aeronautical and space technology constantly develops, this field requires also to improve constantly to cable, not only requires cable to reach the high flame retardant requirement, also will reach environmental requirement, and cable is also soft, is convenient to mobile.And material in the past can not reach requirements such as environment protection high flame resistance and softness.

The utility model content:

At above-mentioned technical problem, the purpose of this utility model provides the soft high temperature-resistant cable of a kind of environment-friendly type Aero-Space, improves the high flame retardant characteristic of cable, satisfies environmental protection requirement.

The technical solution of the utility model is as follows:

The soft high temperature-resistant cable of environment-friendly type Aero-Space, the conductor wire core of two parallel distributions, it is characterized in that: described conductor wire core adopts to be made up of 7 strands of conductors, 7 strands of conductors wherein 6 strands of peripheral conductors are evenly distributed on 1 burst of center conductor periphery, 6 strands of peripheral conductors have 25 stranded formations of lead respectively, and 1 strand of center conductor constitutes by 38 thin wires are stranded; The conductor wire core of two parallel distributions wraps up respectively outward by there being insulating barrier to constitute cable core, and cable core is surrounded with the belting layer that high flame resistance, low smoke Halogen band constitutes outward, is filled with rock wool between belting layer and the cable core, and the outer extrusion moulding of belting layer has restrictive coating.

The soft high temperature-resistant cable of described environment-friendly type Aero-Space is characterized in that: it is low smoke halogen-free flame-retardant polyolefin-150 that described insulating barrier and restrictive coating all adopt material.

The utility model has the advantages that:

The utility model conductor wire core is combined by the multiply flexible conductor, low smoke halogen-free flame-retardant polyolefin-150 is adopted in insulation, fill the rock wool material that adopts utmost point difficult to burn, wrapped employing high flame resistance, low smoke Halogen band, sheath is low smoke halogen-free flame-retardant polyolefin-150 also, the utility model product can be widely used in aerospace field, has excellent characteristics such as high temperature resistant, environmental protection, softness.

Description of drawings:

Fig. 1 is structural representation of the present utility model.

Embodiment:

Referring to Fig. 1:
