Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings, and the protection scope of the present invention is not limited to the following:

[0034] A production process for a flexible mineral insulation fireproof pre-branch cable branch head, which comprises the following steps:

[0035] S1. Preparation before crimping the branch head, including the following steps:

[0036] S1 (I), segment the main cable 1 and branch cable 2 according to the length of the drawing;

[0037] S1(II), such as Figure 1~2 As shown in the figure, strip the copper sheath 3 at the branch connector of the branch cable 2. The stripped length of the copper sheath 3 is L5, and the two ends of the copper sheath 3 are rolled outwards, and polished to remove the sharp edges. Corner burr to avoid piercing, crushing the insulating layer, preventing voltage breakdown and tip discharge;

[0038] S1(III), such as Figure 1~2 As shown, strip the copper sheat...

Abstract

The invention discloses a flexible mineral insulation fireproof pre-branched cable branching head production process. The process comprises the following steps of S1, making preparation before branching head crimping; S2, closely pressing a wire core joint; S3, wrapping a wire core joint; S4, wrapping a cable core; and S5, performing low-smoke no-halogen forming of a pre-branched head. The flexible mineral insulation fireproof pre-branched cable branching head production process has beneficial effects of simple production process, insulating performance, heat-insulating and fireproof performance, multilayer wrapping, excellent heat-insulating and fireproof effect, effective cable core punching prevention, and reliable insurance for conduction of a copper sheath.

Description

technical field [0001] The invention relates to the technical field of the production of fire-proof pre-branch cable branch heads, in particular to a production process of a flexible mineral insulation fire-proof pre-branch cable branch head. Background technique [0002] Scope of use of pre-branch cables: Pre-branch cables are widely used in residential buildings, office buildings, office buildings, large public places and other densely populated places. In recent years, there have been many fires in high-rise buildings and commercial buildings in China. The fire caused the power failure of the lighting circuit and the stop of the elevator. The power supply could not be transmitted normally, which made it difficult to escape and caused heavy losses to people's lives and properties. Therefore, The importance of fire protection is gradually highlighted. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, ...
