Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable protection tubes, in particular to a multi-core, unequal-section, high-temperature-resistant and fire-proof cable protection tube. Background Art
[0002] Cable protection tubes refer to metal protection tubes with a certain mechanical strength to prevent cables from being damaged. Cable protection tubes are mainly installed in areas where communication cables and power lines intersect to prevent power line breaks and short circuits, which would cause communication cables and wire ropes to become electrified. This protects cables, switches, and machine boards, and even the entire machine from being burned out. It also plays a certain role in isolating the power line magnetic field interference.
[0003] Traditional protective tubes that are not resistant to high temperatures or fireproof have a limited operating temperature range and cannot withstand high temperature environments. They may cause the insulation layer to age, soften, or even melt. They do not have a special fireproof layer or flame retardant material. In the event of a fire, flames are easy to spread and the safety is poor. They lack a metal braided layer or a reinforcement layer and are susceptible to external physical damage and mechanical impact. They lack a conductive layer and cannot provide electromagnetic shielding or electrostatic discharge protection, which may affect the stability and safety of the cable. The lack of an identification layer or a non-durable outer sheath increases the difficulty of maintenance and management.
[0004] In view of this, there is an urgent need for a multi-core unequal cross-section high-temperature resistant and fireproof cable protection tube to improve the shortcomings of the existing technology. Utility Model Content

[0007] As a further improvement of this technical solution, the insulating layer is made of high-temperature cross-linked polyethylene material, and the insulating layer is used to protect the battery core. The fireproof layer is made of silicone rubber material, and the fireproof layer is used to prevent the spread of flames in case of fire.

[0016] The above working principle: First, the insulating layer 2 protects the battery core 1 from damage, and the fireproof layer 3 prevents the spread of flames in the event of a fire and prevents the fire from expanding. The metal braided layer 4, the outer sheath 5, the reinforcement layer 6 and the conductive layer 7 increase the mechanical strength and durability of the cable, can protect the cable from physical damage and external impact, can provide electromagnetic shielding effect, prevent the influence of external electromagnetic interference on the cable, and can also reduce the risk of electrostatic discharge. The barrier layer 8 and the sealing layer 9 increase the stability and durability of the protective tube, so that it is not corroded by external moisture or chemicals during use, thereby maintaining its performance and life.
[0017] In order to be resistant to high temperatures and fire, in this embodiment, the insulating layer 2 is made of high-temperature cross-linked polyethylene material, and the insulating layer 2 is used to protect the battery core 1. The fireproof layer 3 is made of silicone rubber material. The fireproof layer 3 prevents the spread of flames in the event of a fire. The material can maintain stability in a high-temperature environment and usually does not degrade or fail at temperatures above 200°C.
[0018] In order to improve the applicability of the sleeve, in this embodiment, the metal braided layer 4 is made of nickel-chromium alloy material, which is used to provide mechanical strength, wear resistance and electromagnetic shielding protection.

The barrier layer 8 is made of polyethylene film material, which is used to increase the stability and durability of the protective tube. The sealing layer 9 is made of polyvinyl chloride material, which is used to protect the cable from external moisture or chemical erosion during use. The identification layer 10 is made of UV high-temperature resistant ink. Since the cable protection tube may be in a complex environment, the outer layer material needs to have sufficient wear resistance and mechanical strength to protect the internal cable from external physical damage.
[0019] In the present embodiment, a multi-core unequal cross-section high-temperature resistant and fireproof cable protection tube is used in practice. First, the insulating layer 2 protects the battery core 1 from damage. The fireproof layer 3 prevents the spread of flames in the event of a fire and prevents the fire from expanding. The material can maintain stability in a high-temperature environment and usually does not degrade or fail at temperatures above 200°C. The metal braided layer 4, outer sheath 5, reinforcement layer 6 and conductive layer 7 increase the mechanical strength and durability of the cable, protect the cable from physical damage and external impact, provide electromagnetic shielding effect, prevent the influence of external electromagnetic interference on the cable, and also reduce the risk of electrostatic discharge. The barrier layer 8 and the sealing layer 9 increase the stability and durability of the protection tube, so that it is not corroded by external moisture or chemicals during use, thereby maintaining its performance and life. Since the cable protection tube may be in a complex environment, the outer layer material needs to have sufficient wear resistance and mechanical strength to protect the internal cable from external physical damage.
