Fire-resistant cables for construction applications

Cable has always been an important application part of flame retardant materials. At present, the main application of ceramicized silicone rubber is medium and low voltage fire-resistant wire and circuit, which is widely used in the insulation layer and outer sheath of power equipment, especially the needs of fire-resistant cables in civil buildings. very large. Solutions can also be designed for cable applications with different needs, such as fire-resistant cables, flame-retardant cables, low-smoke cables, low-toxicity cables, and low-corrosive cables.

New energy vehicle cable

Silicone materials have always been an important part of automobile manufacturing and are widely used in various parts of automobiles, such as airbag coatings, power transmission seals, gaskets, hoses, windshield liners, automotive engine seals, point Fire wire and coil sheath, automotive turbocharger tube cooling tube, sealing and protection of automotive components, etc.

Compared with traditional fuel vehicles, hybrid and pure electric vehicles can greatly save energy. However, compared with traditional fuel vehicles, new energy vehicles have added many high-voltage accessories, such as power batteries, high-voltage power distribution boxes, drive motors, motor controllers, etc., which increases the need for vehicle cables.


Demand promotes progress. At present, the main insulation materials for automotive power cables on the market are cross-linked polyolefins and thermoplastic elastomers. The heat resistance of cross-linked polyolefin materials can reach 150 ℃, but the material properties are relatively hard, installation is difficult, and radiation cross-linking is required, and the process is complicated. The heat resistance of thermoplastic elastomer materials does not exceed 125 °C, the temperature level is low, and the long-term use of the material cable will have the risk of cracking, and the quality is difficult to guarantee.

Based on the comprehensive properties of ceramic silicone rubber: high and low temperature resistance, excellent electrical insulation; large wire current carrying capacity of silicone rubber, saving conductor cross-section, and can meet the requirements of long-term full-load operation; flame retardants can be added to meet the requirements of fire resistance; Easy to install in limited space, high flexibility. Compared with the currently used cross-linked polyolefin and thermoplastic elastic materials, it is more suitable for the needs of new energy vehicle power cables. And in special cases, when it is required to carry an instantaneous large current, the cable needs to have a short-term overload capacity, and the ceramic silicon rubber cable has a good overload capacity.

New energy vehicle wiring harness seal

Hybrid and pure electric vehicles need to be equipped with more wiring harnesses and sensors, and wiring harness seals play a vital role in facilitating wiring harness installation and sealing. As the central nervous system of the automobile, the automobile wiring harness is the carrier of automobile energy and various signal transmission.

As global energy becomes increasingly tense and environmental issues are imminent, new energy vehicles will surely become the top priority of the future development of the global auto industry. Various countries are taking the reduction of fuel vehicles as the goal of the future development of the automotive industry, and ceramic silicon rubber has a great voice in the application of fire-retardant and flame retardant parts for new energy vehicles. shine.
