AI Technical Summary

Problems solved by technology

[0007] The disadvantage of this kind of woven belt is that it is very troublesome to manufacture and very unstable, so this kind of woven belt is difficult to handle when strapping
Because this type of woven tape is prone to slippage, the winding tension required when winding the transformer coil is difficult to maintain

Embodiment Construction

[0013] FIG. 1 shows a multi-parallel wire 1 which is used, for example, as a twisted wire in a transformer winding. The multi-channel parallel line is composed of many rectangular flat sub-lines 3 arranged in two parallel stacks 4 . A paper strip 5 can be inserted between the two stacks 4 . Each branch line 3 is coated with an insulating varnish layer. The branch lines 3 are gently bent by bending at predetermined intervals, so that their positions within the overall cross-section of the multi-way parallel line 1 are regularly changed at similarly short intervals. The bending point is indicated by reference numeral 7 in FIG. 1 .

[0014] In order to improve the stability of the multi-way parallel line 1, it adds a binding made of a band 8 (see figure 2 ), with many perforations or holes 9 in the belt. The tape 8 is wrapped around the multiple parallel wire 1 with a twist pitch 1 which is greater than the width b of the tape 8 . Perforations or holes 9 are preferably great...

Abstract

The multiple parallel conductor (1) has a number of individually electrically isolated electrical sub-conductors that have a common enclosing wrapping material in the form of a perforated strip (8) made of a material resistant to transformer oil. The strip can be made of a cellulose-based material.

Description

technical field [0001] The invention relates to a multi-channel parallel line. Background technique [0002] Large cross-section electrical conductors for electrical installations and machines such as transformer windings are divided into a number of electrically insulated sub-wires which are connected in parallel at their ends. In so-called twisted wires, rectangular copper or aluminum partial wires are combined to form a substantially rectangular overall cross section. In order to keep the influence of the current skin effect as low as possible, the positions of the partial wires within the total cross-section of the twisted wire are swapped along the length of the twisted wire, if necessary repeatedly. For this purpose, the partial wires are bent at predetermined positions by means of suitable tools and the position of the partial wires within the twisted wire is changed accordingly. [0003] Such a method is known from DE-3923448C1. [0004] The twisted wires are usua...
