Fire-resisting plastic insulating conductive band

Abstract

A retardant plastic insulating conduction band used in outdoor lead-in wire of electric control cabins and transformers includes ribbon copper with at least two closely stacked sheet coppers 0.5-1.0 mm thick and 6mm-50mm wide. The said ribbon copper is coated with retardant plastic insulation layer. Advantages: soft bended and easy coated which does not crack the insulation protection medium wrapping conductors and reducer flame tempeture, steps heat and oxidation transfer channel once bumps into fire, the length of it can be processed freely, copper sheets are bound tightly without slot.

Description

technical field [0001] The invention relates to a flame-retardant plastic insulating conductive tape, in particular to an outdoor lead-in wire for electrical control cabinets and various transformers, and belongs to a fixed connection wire for electric energy transmission in the electrical field. Background technique [0002] So far, in the outdoor lead-in lines of various electrical control cabinets and transformers, copper rods with excellent electrical conductivity, copper cables twisted into strands, etc. are used as fixed connection lines for power transmission, but more A single piece of copper strip, because the copper rod and copper cable have the defect that it is difficult to withstand high current due to the small contact area of ​​the connection, but the copper strip is not. However, the copper strip also has the disadvantage that it is not suitable for bending, so it is a thorny problem that people are eager to solve to make the copper strip have the softness th...

Problems solved by technology

There are disadvantages: 1. In order to combine the multilayer flat conductors 11 of each unit, a large amount of bonding material 13 is used, thereby increasing the volume of the wire 10; 2. For the multilayer flat conductor 11 of a unit, The layers are not superimposed and combined together. It is because of this structure that not only the flexibility is limited, but also it cannot be used as an electrical control cabinet under high current and various transformers.

Disadvantages of the flat cable of this structure 1. Put it into use after folding and cannot be bent during use, otherwise creases and fractures will easily occur at the connecting part 3

However, the connecting cables required for the outdoor lead-in wires of electrical control cabinets and various transformers should reflect the flexibility; Both sides are insulated from each other by plastic coating, therefore, by image 3 It can be seen that what it constitutes in essence is that several identical units 4a, 4b, 4c, 4d are formed through the connection part 3 into a whole thin strip 1a, that is, a thin strip type wire, because the units 4a, 4b , 4c, 4d are not electrically connected between the superimposed surfaces, but are only electrically connected by the connecting portion 3 at each side edge; 3. The outer layer of this multilayer flat cable has no flame-retardant plastic protection, and the resistance Flammability cannot be guaranteed; 4. The folded layers are in a fluffy state
