Embodiment Construction

[0017] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0018] Depend on figure 1 It can be seen that the fireproof control cable of the present invention includes: a wire core 1; an insulating layer 2 is coated on the outside of the wire core 1; the number of the wire core 1 is between 2-61; 2-61 wires The outer layer of the core 1 twisted cable is the metal tube shielding layer 3; the outer layer of the metal tube shielding layer 3 is the oxygen barrier layer 4; the outer layer of the oxygen barrier layer 4 is the fire-resistant and impact-resistant layer 5; The outer layer is the outer sheath.

[0019] The technical feature of the present invention is that structure, and the material that adopts in every layer can all be bought in the market, as: the material of outer sheath in the present invention is the conventional low-smoke halogen-free polyolefin that adopts in the prior art; The prior art...

Abstract

The present invention relates to a fireproof control cable and a manufacturing method thereof. The fireproof control cable of the present invention comprises: a wire core; an insulating layer is coated on the outside of the wire core; and the number of the wire cores is between 2 and 61 ; The outer layer of the cable stranded by 2-61 wire cores is the metal tube shielding layer; the outer layer of the metal tube shielding layer is an oxygen barrier layer; the outer layer of the oxygen barrier layer is a fire-resistant and impact-resistant layer; The outer layer is the outer sheath; the beneficial effects of the present invention are: the fire-resistant control cable has passed the C, W, and Z-level tests of BS6387, high voltage level, good shielding performance, good flame retardancy, large carrying capacity, and allowable short-circuit current Large and other characteristics, can meet the needs of high temperature equipment and fire control system.

Description

technical field [0001] The invention relates to a control cable and a manufacturing method thereof, in particular to a fireproof control cable and a manufacturing method thereof. Background technique [0002] Common fire-resistant control cables in the prior art generally use polyvinyl chloride or cross-linked polyethylene as insulation, the fire-resistant layer is generally phlogopite tape, and the sheath material is polyvinyl chloride. Due to its structural characteristics, this fire-resistant control cable has a fire-resistant temperature of 750-800°C and a fire-resistant time of 90 minutes, and its fire-resistant reliability is not strong. At the same time, ordinary fire-resistant control cables do not have the functions of anti-collision and anti-spray. In the event of a fire, ordinary fire-resistant control cables cannot guarantee that the line will continue to work, and it is difficult to fight for a longer time for escape and rescue. [0003] However, the copper co...
