My country’s key cities such as Beijing and Shanghai have clearly stipulated that important buildings prohibit the use of polyvinyl chloride fluoroplastic high-temperature wires to avoid a large amount of smoke and chlorine in the event of a fire, causing more casualties, and adopting halogen-free low-smoke cross-linked polyolefin insulation Wires and cables have become local regulations in these areas. With the increase in environmental protection awareness, the application of such wires will gradually expand. With the EU promulgation of the ROHS directive, the research and development and large-scale adoption of eco-friendly wires and cables has become an international trend. At present, the application of flame-retardant and fire-resistant cables at home and abroad has expanded to many fields, such as mines, general rubber-sheathed cables, elevator cables, and cables for household appliances all have different levels of flame retardant requirements.

As the global oil and natural gas energy sources are becoming more and more tense, land exploration has begun to turn to the marine field on a large scale, and the scale of offshore oil and natural gas engineering projects continues to expand. It is necessary to move from land to offshore oil platforms, and power and communication between platforms. The transmission and feedback and control of technical data have made the demand for integrated submarine cables continue to grow. According to my country's oil development plan, my country's offshore oil development will usher in a period of rapid development. In the next five years, 120 billion yuan will be invested in offshore oil development.

The new low-inductance cable also includes the cable and the connector fixed on the cable end, and the fluoroplastic high-temperature wire is also composed of the positive cable core and the negative cable core in the outer rubber tube. Since this type of low-inductance cable is generally used in applications where the voltage is 25-50V and the current is between 7000-12000A, the short-circuit conductivity of the cooling water in the cable is basically negligible, so there is no The rubber hose that separates the positive cable core and the negative cable core is used, but a special core frame with a cross-section of the spoke-shaped (commonly known as "plum core") is set up between the "wheel center" and the adjacent "spokes". The space formed is longitudinal grooves along the axial direction. The longitudinal grooves on the core frame are the same as the total number of positive cable cores of the cable. The cable part is placed on the positive cable core and the negative cable core respectively. The inner device of the longitudinal groove of the core frame is formed in the outer rubber tube.

In the next few years, the national cable manufacturing industry will continue to experience a difficult stage. There must be a group of backbone forces who always concentrate on the development of the cable industry and support the banner of China's national cable industry. The professional development of silicone braided wire can extend along the upstream and downstream of the product and industrial chain, and the development space is actually huge.

When many Chinese companies open up foreign markets, we found that in addition to a series of trade protection barriers, foreign countries often set up technical barriers through the formulation of technical standards.
