Abstract

The invention is a flexible fireproof cable and its producing process as well as its producing equipment. It uniformly distributes a group of metal wire cores, which are mutually isolated and coated in the vertical direction by mica tape insulating layer and then coats a metal tape outside, the metal tape is folded annularly and closed vertically by a welding line, thus composing the flexible fireproof cable. If it needs a better bending property, it can roll lines on a smooth metal protective cover. Its producing equipment is composed mainly of a twisted wire winder, a cable winder and a metal protective cover coat-welding machine connected in series in sequence. It solves the problems of high temperature resistance, safety and environmental protection as well as process complexity, cable hardness, cable length, and insulating resistance. It can not fire, burn and produce smoke frog and harmful substances even if the surrounding substances have been firing and burning, so it is a permanent fireproof safe environmental protection cable.

Description

[0001] (1) Technology area

[0002] The invention belongs to the field of cables, in particular to a power cable and its production process and production equipment. (2) Background technology

[0003] Existing power cables are usually insulated with organic materials such as rubber, plastic, etc. When the power cable line catches fire, the insulating material will be completely burned, and smoke and harmful substances will be emitted. Some improved organic material insulated cables, although the smoke will be significantly reduced when burning, and the release of harmful substances will be improved, but once the fire burns, the wire and cable line will not continue to work. Insulated cables with metal oxides such as magnesium oxide powder as insulation and metal tubes as sheaths improve the above shortcomings, but the manufacturing method is complicated, the process is long, and there are many equipments, such as image 3 Shown: Firstly, MgO ceramic pillars must be threaded on...
