Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of network cables, and in particular to the technical field of a silicone rubber and high-density PE double-insulated CAT5EUTP fire-resistant monitoring network cable. Background Technology
[0002] With the rapid development of modern information technology, network monitoring systems are being used more and more widely. From home security monitoring to remote monitoring of large industrial facilities, all rely on stable and efficient network transmission. However, in practical applications, network cables often need to be deployed in complex and ever-changing environments, such as high temperatures, humidity, and even extreme conditions like fires. While traditional CAT5EUTP network cables can meet basic network transmission requirements, their fire resistance and transmission stability still need improvement. This is especially true in situations where network security and stability requirements are extremely high, such as data centers and monitoring systems of large enterprises. If a network cable is damaged in a fire, it will not only cause data transmission interruption but may also lead to greater safety hazards. Therefore, it is particularly important to develop a network cable that has both excellent transmission performance and can maintain a certain level of fire resistance in the event of a fire. Summary of the Invention
[0003] The purpose of this invention is to solve the problems in the existing technology and propose a CAT5E UTP fire-resistant monitoring network cable with double insulation of silicone rubber and high-density PE. The network cable can be combined with the inner high-density PE insulation sheath and the outer silicone rubber insulation sheath, which not only ensures the transmission performance of the core wire, but also provides additional fire protection.
[0004] To achieve the above objectives, this utility model proposes a CAT5E UTP fire-resistant monitoring network cable with double insulation of silicone rubber and high-density PE, comprising twisted pair cores, a high-density PE insulation sheath, a silicone rubber insulation sheath, and a high flame-retardant sheath. Each twisted pair core is covered with a high-density PE insulation sheath, and the high-density PE insulation sheath is covered with a silicone rubber insulation sheath. There are four pairs of twisted pair cores, and each pair of twisted pair cores is covered with a high flame-retardant sheath.
[0005] Preferably, the diameter tolerance of the twisted pair core is less than 3 μm and the concentricity is greater than 99%.
[0006] Preferably, the outside of the twisted pair core is covered with an insulating rubber sheath.
[0007] Preferably, the high flame-retardant sheath is a high flame-retardant, low-smoke, halogen-free polyolefin sheath.
[0008] Preferably, the high flame-retardant sheath contains a number of tensile wire bundles evenly arranged inside.
[0009] Preferably, the silicone rubber insulating sleeve and the high-density PE insulating sleeve are tightly fitted together.
[0010] Preferably, the twisting direction of the twisted pair cores is opposite to the cabling and bundling direction.
[0011] The beneficial effects of this utility model are as follows: This utility model combines twisted pair cores, high-density PE insulation sheaths, silicone rubber insulation sheaths, and high flame-retardant sheaths. Through experimental optimization, the high-density PE insulation sheath has excellent insulation performance and mechanical strength, which can effectively ensure the transmission performance and stability of the core wire. The silicone rubber insulation sheath has excellent fire resistance and high temperature resistance, and can maintain a certain degree of stability and insulation in high temperature and fire environments. The combination of the inner high-density PE insulation sheath and the outer silicone rubber insulation sheath not only ensures the transmission performance of the core wire, but also provides additional fire protection.
[0012] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description
