Problems solved by technology

[0002] Emergency charging vehicles and emergency generator vehicles used for power grid repairs, field operations, and field lighting are playing an increasingly important role. In order to ensure the stability of power supply, there are requirements for cables such as reels, color separation, and flame retardancy. , the existing cables cannot meet the requirements of emergency vehicles well, so it is necessary to design a flexible cable for emergency vehicles that is easy to use and simple to produce, its production process and a special two-color extruder

Embodiment Construction

[0050] See figure 1 , is the emergency vehicle flexible cable of this embodiment, including a combined conductor 1, an insulating shielding layer 2, a shielding strengthening layer 3 and a sheath 4 wrapped around the combined conductor 1 from the inside to the outside in turn, and the two ends of the cable are respectively arranged Quick plug 5. The surface of the sheath 4 is embedded with a phase-separated ribbon 4-1 of a color different from that of the sheath.

[0051] The combined conductor 1 includes seven middle-strand wire bundles. The middle-strand wire bundle includes a steel core 1-1 and 6 small wire bundles 1-2 twisted outside the steel core 1-1. The pitch ratio of 1-2 small-strand wire bundles is 20-24, the pitch-diameter ratio of 16-18 is controlled by the twisting of medium-strand wire bundles, and the pitch-diameter ratio of 14-16 is controlled by 1 twisting of combined conductors. The pitch-to-diameter ratio of the cable is appropriate, the conductor structu...

Abstract

The invention discloses a flexible cable for emergency vehicles and a production process thereof and a special double-color extruder. The flexible cable comprises a combined conductor, an insulating shielding layer, a shielding reinforcing layer and a sheath which wrap the combined conductor in turn from inside to outside, and fast plugs which are respectively arranged at the two ends of the cable. The surface of the sheath is embedded with a phase separation color band in a color different from that of the sheath. The cable for emergency vehicles has excellent tensile strength, anti-torsion performance, fire resistance, wear resistance and shielding performance. The cable is provided with the phase separation color band on the surface, so that the cable can be distinguished quickly, conveniently and effectively and is not easy to be confused. Meanwhile, the fast plugs are respectively arranged at the two ends of the cable, the fast plugs can be quickly connected with the plugs on an emergency vehicle for use when the emergency vehicle needs the cable. The cable is very convenient and reliable.

Description

technical field [0001] The invention relates to cables, in particular to a flexible cable for emergency vehicles, its production process and a special two-color extruder. Background technique [0002] Emergency charging vehicles and emergency generator vehicles used for power grid repairs, field operations, and field lighting are playing an increasingly important role. In order to ensure the stability of power supply, there are requirements for cables such as reels, color phase separation, and flame retardancy. , the existing cables can not meet the requirements of emergency vehicles, so it is necessary to design a flexible cable for emergency vehicles that is easy to use and easy to produce, its production process and a special two-color extruder. Contents of the invention [0003] The object of the present invention is to provide a flexible cable for emergency vehicle with easy use and simple production, its production process and special two-color extruder. [0004] Th...
