High temperature resistant shielded cable KFFP-4 * 1.5MM2

High temperature resistant shielded cable KFFP-4 * 1.5MM2

Main applications
Fluoroplastic insulated high-temperature resistant control cables are suitable for connecting wires of control, monitoring circuits, electrical instruments, and transmission lines of automatic control systems with AC rated voltage of 450/750V and below.The product has excellent properties such as oil resistance, waterproofing, wear resistance, acid resistance to various chemical reagents and corrosive gases, aging resistance, and non combustion; This product is mainly suitable for use as a transmission line for electrical instruments and automation control systems in harsh environments such as high temperature, low temperature, acid, alkali, oil, water, and corrosive gases in industrial and mining enterprises such as power generation, metallurgy, petroleum, and chemical industry. Fluoroplastic insulated and sheathed high temperature resistant control cables are made of perfluoroethylene propylene or modified polytetrafluoroethylene materials, which have a higher heat resistance level than ordinary control cables.

Installation and construction of wires and cables
High temperature resistant shielded cable KFFP-4 * 1.5MM2The design and construction of wire and cable laying and installation should be carried out in accordance with relevant regulations such as GB 50217-94 "Code for Design of Cables in Power Engineering", and necessary cable accessories (terminals and joints) should be used. The operation quality, safety, and reliability of the power supply system are not only related to the quality of the wires and cables themselves, but also to the construction quality of cable accessories and lines.

Through statistical analysis of line faults, it is found that faults caused by construction, installation, and connection factors are often much more likely than those caused by defects in the wire and cable body. Therefore, it is necessary to correctly select wires, cables, and supporting accessories. In addition to designing and constructing according to regulatory requirements, it is also necessary to
Attention should be paid to the following aspects:
1> Cable laying and installation should be carried out by qualified professional units or personnel. Construction and installation that do not comply with relevant regulatory requirements may result in the cable system not functioning properly.
2> When laying cables manually, the command and control rhythm should be unified, with one person carrying the cable every 1.5 to 3 meters, pulling and slowly releasing it.
3> When mechanically laying cables, cable laying machines are generally used and necessary traction tools are equipped. The traction force is appropriate and evenly controlled to avoid damaging the cables.
4> Before laying the cable, it is necessary to check the appearance of the cable and whether the head is intact. When laying, pay attention to the rotation direction of the cable reel and do not flatten or scratch the outer sheath of the cable. In winter, do not straighten the cable by hitting it to avoid insulation and sheath cracking.
5> The bending radius of the cable during laying should be greater than the specified value. Before and after cable laying and installation, use a 1000V megohmmeter to measure the insulation resistance between each conductor of the cable to ensure it is normal. Adjust the measurement results appropriately based on the cable model, length, and ambient temperature. For small-sized (solid core conductors below 10mm ²) cables, the continuity of the conductors should also be measured.
6> When laying cables directly, attention should be paid to soil conditions. Generally, the burial depth of cables under buildings should not be less than 0.3 meters. For softer or more complex environments such as farmland, construction sites, or roads, a certain burial depth (0.7-1 meters) should be established to prevent accidental damage to directly buried cables. If necessary, clear signs should be erected.
