Problems solved by technology

The inner conductor of the elevator special cable signal line has only one shielding layer and the shielding layer is single, the shielding effect is not complete, the transmission of data is not stable enough, and the quality is not high
Moreover, the special cable for the elevator has only one tensile load-bearing rope, which has poor bending and tensile properties and a short service life.

Abstract

The invention relates to a special surveillance video comprehensive line for an elevator. The special surveillance video comprehensive line comprises an outer sheath, a signal line arranged in the outer sheath, a power line and two reinforcing ribs, wherein the reinforcing ribs are symmetrically distributed on the two sides of the outer sheath; the signal line and the power line are arranged between the two reinforcing ribs; and the signal line comprises a signal line inner conductor, a signal line inner conductor insulating layer covering the signal line inner conductor, a first shielding layer covering the signal line inner conductor insulating layer, a signal line sheath layer covering the first shielding layer and a second shielding layer covering the signal line sheath layer. Each of the first shielding layer and the second shielding layer is composed of an aluminum foil shielding layer and a copper wire shielding layer. The power line is composed of a power line inner conductor and a power line inner conductor insulating layer covering the power line inner conductor; filling strips are arranged on the left and right sides of the power line; and the power line and the filler strips are hinged. The special surveillance video comprehensive line for the elevator has good shielding effects on interference signals, stable data transmission, high quality, better bending resistance and tensile property and long service life.

Description

technical field [0001] The invention relates to a cable, in particular to an elevator dedicated surveillance video integrated cable. Background technique [0002] The elevator is the main vertical means of transportation in the modern building, and the elevator is equipped with a dedicated surveillance video integrated line inside the elevator. Elevator dedicated monitoring video integrated cable must have a good shielding effect, shielding from external interference, and providing a good protective environment for the transmission of core signal. At the same time, the elevator dedicated surveillance video integrated cable must also ensure the bending and tensile properties. During the elevator’s use, the elevator moves vertically up and down, and it is bent and stretched back and forth. Bending and stress will cause the elevator dedicated surveillance video composite line to stretch until it finally breaks. The elevator dedicated surveillance video composite cable has high...
