It is well-known that optical fiber cable water penetration is an environmental performance index strictly required by users. However, ladle optical fiber cable is easy to seep in the steel lap joint. In the traditional method, the hot melt adhesive is generally used to fill the lap joint, . However, there are many shortcomings of the traditional methods, such as adding less than the amount of plastic will cause water seepage occurs, the amount of plastic plus excess will cause the package extrusion occurs when the package, it is difficult to control the amount of glue; also because the surface of the strip poly Ester film bond is not strong at the core accumulation caused by the sheath out of the phenomenon. The purpose of stainless steel heat treatment, above all, its corrosion resistance, acid resistance. So, even if its heat treatment is an important process, it is not an exaggeration. In addition, there is also the use of 304 stainless steel low temperature, heat, wear-resistant or magnetic properties. These properties are also dominated by heat treatment. The new technology adopts the principle of high-frequency induction heating equipment to melt the surface of the steel strip, which not only makes the bonding of the steel strip firmly, but also improves the bonding strength between the steel strip and the sheath and thoroughly solves the problem of seepage and protection Set out the package phenomenon. The principle of high-frequency induction heating equipment is the molecular material under the action of high-frequency electric field polarization phenomenon, and according to the direction of the electric field, due to the high-frequency electric field to change the molecular orientation at a very fast rate, the dielectric material will be due to dielectric Loss and fever. The high-frequency current flows to a heating coil wound around a ring or other shape (usually made of a copper tube). Thereby generating a strong magnetic field of instantaneous change of polarity in the coil. When the heated material such as metal is placed in the coil, the magnetic flux passes through the entire heated material and a large vortex is generated in the opposite direction from the heating current in the heated material Current, due to the heated material within the resistance Joule heat, so that the rapid increase in temperature of the material itself, which is the principle of induction heating.
