Due to the special performance of special cables, the manufacturing technology of their production equipment is constantly making breakthroughs. Taking fire-resistant cables as an example, according to the data in “Frontiers of Cable Technology”, the new ceramic silicone rubber material plays a key role in the manufacturing of fire-resistant cables.
Ceramic silicone rubber has the elasticity and other characteristics of ordinary rubber at normal temperature, but it will quickly transform into a hard ceramic-like substance under high-temperature flames. Its composition contains elements such as silicon and oxygen. Under high temperature, the silicon-oxygen bond is restructured to form a ceramic structure, which can effectively block the spread of flames and play a role in heat insulation and fire prevention. In terms of production equipment, advanced high-temperature sintering process equipment is used to accurately control temperature and pressure to ensure that the ceramic silicone rubber is evenly distributed on the cable insulation layer and forms a stable structure. For the manufacturing of waterproof cable equipment, a special sealed extrusion mold is the key technology. This mold adopts high-precision processing technology. The flow channel design of the mold is reasonable, which can make the waterproof material tightly wrap the cable core and prevent water from invading. In the manufacturing of deep-sea cables, the equipment also needs to have the ability to withstand high water pressure. Through special armor structure design and material selection, such as high-strength alloy steel armor, it can not only protect the internal structure of the cable but also resist external water pressure. Some enterprises have successfully produced cable products that meet the needs of special environments through researching and developing special cable equipment manufacturing technologies, playing an important role in the fields of energy and communications.
