Abstract

The invention discloses a bunched cable suitable for outdoor video monitoring application, and the cable comprises three cable cores in a triangular shape, and four steel ropes in a Y shape. The distances between each two circle centers of three cable cores are equal. Three of the four steel ropes are respectively distributed between each two circle centers of three cable cores, and the other steel rope is distributed in the center of the three cable cores. A copper core conductor is sequentially wrapped by a second insulating layer, an aluminum foil mylar layer, a tinned copper wire braided layer, and a wrapping layer. Three cable cores and the four steel ropes are sequentially wrapped by a first insulating layer, a braided mesh shielding layer, an alloy sleeve layer, and a sheath layer. The diameter of each steel rope is one fourth of the diameter of each cable core. The bunched cable is suitable for the wiring of outdoor traffic and security monitoring systems, such as a skynet. The bunched cable is high in strength, is resistant to grinding, and can adapt to big wind, accidental pull, and grinding by a vehicle on the ground.

Description

technical field [0001] The invention relates to a bundled cable, in particular to a bundled cable for video monitoring. Background technique [0002] Video surveillance is an important part of modern production equipment, safety monitoring, logistics network construction and other fields. However, outdoors, the temperature difference between high and low temperatures varies greatly, snow and ice are often accumulated in winter, the flame retardant requirements are high in summer, strong winds and typhoons are strong, and vehicles on the ground are frequently rolled over. These conditions put forward strict requirements for video cables. [0003] Existing video signal lines, especially video surveillance connection signal lines, are mainly composed of conductors and insulating layers coated from the inside to the outside of the conductors, the first wire braided mesh shielding layer, and the second metal wire braided mesh shielding layer. and outer sheath. The insulating la...
