Example Embodiment

[0038]Example one

[0039]A compressive thermal utility wire cable, including fireproof cladding layer 1, and a multi-main core 2 and a reinforcing core tube 3 are provided in the fire-resistant cladding layer 1, and the reinforcing core tube 3 is disposed at multiple main cores 2. Between, and the plurality of main cores 2 are equipped with a plurality of compressive support frames 4, and the reinforcing core tube 3 is in contact with the inner wall of the fire-resistant cladding layer 1 through the plurality of compressive support frame 4 compressive support frame 4. The outer surface of the fire release layer 1 has a compressive flame retardant layer.

[0040]Wherein, the main core 2 includes a plurality of conductor 6, and the outer cover of the conductor 6 is covered with an insulating layer 7, and the outer coating of the insulating layer 7 has a braided shield layer 8, and the outer coating of the braided shield layer 8 has a high temperature loose tube 9. .

[0041]Among them, the co...

Example Embodiment

[0047]Example two

[0048]A method for preparing pressure-resistant and heat-resistant practical wire and cable includes the following specific implementation steps:

[0049]Step one, twist a plurality of nickel-plated copper wires to form a conductor 6;

[0050]Step 2: Extruding a layer of ceramic silicon rubber on the outer periphery of the conductor 6 to form an insulating layer 7;

[0051]Step three, twist a plurality of insulated wire cores to form a package body and cover the braided layer of silver-plated copper wire to form a braided shielding layer 8. The braided shielding layer 8 is coated with a high-bulk glass fiber tube and coated with oxidation Iron red silica gel forms a high-temperature resistant loose tube 9 to form the main core;

[0052]Step 4: Set a plurality of vent holes 13 on the PTFE hose to form a reinforced core tube 3, fix a plurality of compressive support frames 4 equidistantly outside the reinforced core tube 3, and pass a plurality of main wire cores through the fixi...

Abstract

The invention discloses a compression and heat resistant practical wire cable, which comprises a fireproof lapped covering, a plurality of main wire cores and a reinforcing core tube are arranged in the fireproof lapped covering, the reinforcing core tube is arranged among the plurality of main wire cores, and a plurality of compression-resistant support frames are arranged among the plurality ofmain wire cores at equal intervals. The reinforcing core tube penetrates through the plurality of compression-resistant support frames to make contact with the inner wall of the fireproof lapped covering, the interior of the fireproof lapped covering is filled with heat-insulating and flame-retardant particles, and the exterior of the fireproof lapped covering is coated with a compression-resistant and flame-retardant layer. The plurality of compression-resistant support frames are arranged on the main wire cores and the reinforcing core tube, so that a good compression-resistant protection effect can be achieved on the wire cable, when the cable is extruded, a polyurethane elastomer material can achieve a protection effect on the main wire cores and the reinforcing core tube, and the problems of short circuit and the like caused by damage of an insulating layer can be avoided; and when the cable is subjected to external impact, an elastic connecting piece can play a role in buffering,so that the stress of the cable can be dispersed, and the flame-retardant outer sheath is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a pressure-resistant and heat-resistant practical wire and cable. Background technique [0002] Wire and cable are used to transmit electric energy, information and wire products to realize electromagnetic energy conversion. In the broad sense, wires and cables are also referred to as cables for short. In the narrow sense, cables refer to insulated cables, which can be defined as: a collection composed of the following parts; one or more insulated cores, and their respective possible coatings. Protective layer and outer sheath, the cable may also have additional uninsulated conductors. [0003] The vast majority of wire and cable products are products with the same cross-sectional shape and long strips, which are determined by the characteristics used to form circuits or coils in systems or equipment. Therefore, to study and analyze the structural composition of cable ...
