High-temperature silica gel connecting wireMade of high-quality silicone rubber and high-purity tinned copper stranded wire, it has the advantages of high and low temperature resistance and insulation, and is widely used in the wiring of household appliances, lighting fixtures, industrial machinery, electric heating products and other high-temperature places. Next, let's introduce the characteristics of high-temperature silica gel connector and how to prevent water from entering the high-temperature silica gel connector.
Main features of high-temperature silica gel connecting wire
The main characteristics of high-temperature silica gel connecting wire are high temperature resistance, insulation, flame resistance, acid and alkali resistance, aging resistance, weather resistance, high strength, high modulus, anti-static, and smooth appearance. They are various, such as fluoroplastic insulated high temperature wire, silicone rubber insulated high temperature wire, high temperature electronic wire, silicone rubber insulated braided wire, multi-core high temperature cable, PEEK wire, mineral insulated flame retardant cable, etc. Silicone rubber high voltage wire, polytetrafluoroethylene high voltage wire and polytetrafluoroethylene wire, nylon sheathed wire, mica high temperature wire, aircraft wax wire.
The appearance of high-temperature silica gel connecting wire shall be smooth and round, with uniform luster, no visible sundries, no mechanical damage, no flattening, and no deviation from the core wire (no more than the specified deviation, bubble blister, bamboo knot, shape distortion, and significant particles). It can be seen that the thickness of the sheath has a certain impact on the quality of the high-temperature silica gel connecting wire. Of course, the thickness of the sheath is not up to standard. If the thickness exceeds the standard, it is also not up to standard.
The material properties of high-temperature silica gel connecting wire are not reflected by the thickness, but by the standard requirements. If a certain index value is not up to standard, it will directly affect the quality of high-temperature silica gel connecting wire. After laying the high-temperature silica gel connecting wire, it will generate heat energy if it is electrified for a long time. The allowable working temperature of the conductor is 70 ℃, and the allowable long-term working temperature of the high-temperature silica gel connecting wire is 180 ℃. In summer, the working temperature will rise. These temperatures will dissipate through the outer jacket. The thickness of the sheath will increase, and the heat energy is difficult to dissipate, which will affect the service life of the high-temperature silica gel connecting wire. Under the effect of heat generation, a series of physical and chemical reactions will occur in the insulation layer, which will lose its original high-quality performance, resulting in a significant decline in the insulation performance, or even a short-circuit fault, affecting the normal operation of the unit.
How to prevent water from entering the high-temperature silica gel connecting line?
1. Do a good job of sealing. The ends of the sawn high-temperature silica gel connecting wire, whether stacked or laid, should be sealed with plastic, and the special sealing sleeve for the high-temperature silica gel connecting wire should be used to prevent moisture infiltration.
2. After the laying of high-temperature silica gel connecting wire, the wire head shall be made immediately to prevent moisture from seeping into the end.
3. Strengthen the management of wire head manufacturing technology. When the cable enters the water, the wire head will be damaged earlier. Therefore, a well-made wire head can extend the overall life of the wire.
4. Use a branch box for storage. The high-temperature silica gel connecting wire should be stored in stages, so that even if some parts are soaked in water, they will not spread to other parts.
