Following the pp-r pipeline system, the tonzo superior pipeline system added new members. In July 2016, the tonzo home installation electrical wiring screening system was officially launched! Completed by tonzo independent research and development of building resistance to electromagnetic interference signal protection casing (and shielding tube, patent number: ZL201420807668.2), by conducting layer is set in the wall of the PVC protective casing, make the protective casing with functions of resistance to electromagnetic interference. At the same time, the outer layer of the shield can maintain good flame retardant and insulation performance.

Nowadays, electronic products and household appliances are developing rapidly. In numerous electronic products and household appliances are the weak part is easily influenced by the magnetic fields produced by high voltage disturbance, caused the TV image blurring, acoustic noise, such as electronic instrument malfunction phenomenon. At present, the family decoration has no effective method for the protection of weak current, and each casing manufacturer only USES color to distinguish between strong and weak electricity, and does not carry out the actual protection of the weak wire. Compared with the commonly used red and blue sleeves in the market, the tonzo shielding tube has the following advantages:
