Abstract
The utility model discloses a comprehensive signal shielded cable for a supercritical power generation central control system, relating to the technical field of cable manufacturing. The comprehensive signal shielded cable for the supercritical power generation central control system comprises at least two groups of insulated conductors. Each insulated conductor is sequentially provided with a wrapping tape, a tinned copper wire braided shielding layer, a polrvinyl chloride isolating layer, a copper strip outer shielding layer and a polrvinyl chloride outer sheathing layer from inside to outside. An anaerobic conductor consists of a conductor and a polrvinyl chloride insulating layer, and the polrvinyl chloride insulating layer is coated outside the conductor. The cable can work at high temperature of 150 DEG C and has high anti-interference performance. The inner shielding layer is soft after the outer shielding layer is removed. The cable can be used indoors in a moving way in a short-distance. The cable is applicable to the connection of a supercritical power generation system and a control chamber.
Description
