Description

A high-performance marine special control cable

Technical field

The utility model relates to a special control cable for ships, which belongs to the technical field of electric wires and cables for electrical equipment.

Background technique

Control cables in electrical equipment are mainly used to transmit control and measurement signals, etc. Commonly used control cables are not strong in flame retardancy, easy to catch fire, and will produce a large amount of toxic and harmful gases when burned, which will not only damage the body of personnel, but also It may corrode nearby equipment and cause greater economic losses. In addition to meeting the transmission performance of a single strand, the control cables used on ships need to meet higher requirements in terms of fire protection: the control cables can maintain the working time as long as possible when burning, so that they can be used in a limited space. Conduct possible rescue efforts.

Utility model content

The problem to be solved by the utility model is to provide a special marine control cable that can maintain a certain working time when the flame is directly burned and will not produce harmful and toxic gases. The special marine control cable meets the environmental protection requirements.

The problem to be solved by the utility model can be realized through the following technical solutions: a high-performance marine special control cable, which is characterized in that it includes seven sets of core cables, filling ropes, wrapping tapes, shielding layers, inner sheaths and outer sheaths Each group of core cables is composed of cross-linked polyethylene (XLPE) insulation layer wrapped around the conductor, the tape is wrapped around the seven groups of core cables, and the filling rope fills the gaps between the core cables of each group. The tape The outer is wrapped with an inner sheath, a shielding layer and an outer sheath in turn; the conductor is a tinned copper conductor or a bare copper conductor, and the shielding layer is a tinned copper wire, a bare copper wire or a galvanized steel wire braided armor layer, The inner sheath and the outer sheath are made of flame-retardant propylene oxide (ZR-PO) or flame-retardant polyolefin (ZR-XLPO) materials.

On the basis of the above, the core cable of the utility model also includes a fire-resistant layer between the conductor and the cross-linked polyethylene (XLPE) insulating layer, so as to further improve the flame-retardant performance of the control cable.

Compared with the prior art, the utility model is equipped with an inner sheath and an outer sheath, which can better prevent the core cable from being damaged by external forces, and on the premise of ensuring the mechanical properties of the cable, it has high flame retardancy, and can be directly damaged by flames. When burning, it can maintain a certain working time without producing harmful and toxic gases, and the cable meets the requirements of environmental protection.

Detailed ways

The high-performance marine special control cable shown in Figure 1 is an embodiment 1 of the present utility model, which includes seven sets of core cables, filling rope 3, wrapping tape 4, shielding layer 6, inner sheath 5 and outer sheath 7. Each group of core cables is composed of XLPE insulation layer 2 wrapped around the conductor 1, the tape 4 is wrapped outside the seven groups of core cables, the filling rope 3 fills the gap between the core cables of each group, and the outside of the tape 4 is wrapped in turn. Sheath 5, shielding layer 6 and outer sheath 7; conductor 1 is tinned copper conductor or bare copper conductor, shielding layer 6 is braided armor layer of tinned copper wire, bare copper wire or galvanized steel wire, inner sheath 5 , The outer sheath 7 is made of ZR-PO or ZR-XLPO material.

The high-performance marine special control cable shown in Figure 2 is Embodiment 2 of the present utility model. The difference between it and Embodiment 1 is that the core cable also includes a refractory layer 8 between the conductor 1 and the XLPE insulating layer 2 .
