Description

A kind of cable for ship

Technical field

The utility model relates to cable production art more particularly to a kind of cables for ship.

Background technique

With the development of the social economy, the infrastructure such as China's electric power, water conservancy, environmental protection investment constantly increases, so that ship Industrial expansion speed increase severely while, people also put forward higher requirements the degree of electric power on ship and automation, because with The dosage for the wire and cable that various power equipments, control unit, instrument and meter match is also growing day by day.

Cable for ship due to its use environment particularity, guaranteeing electric property and under the premise of mechanical performance, people Proposing outer diameter to it should be as small as possible, and weight is light as far as possible, Halogen, low cigarette and low toxicity etc. require.

Cable for ship can be divided mainly into power cable, control cable and signal-transmitting cable；In actual production and application Also the different electricity of a plurality of function is individually mainly laid on same line direction to have a single function based on type cable Cable, lightweight and outer diameter purpose small as far as possible, and the heavy workload laid just much is not achieved in this, and the construction time is longer, occupies Space is larger, and tracing it to its cause mainly has following several respects:

1, people are less to the comprehensive cable research transmitted power, control and signal etc. together with combining properties, Also simple function cable is relatively mostly used when selection；

2, multi-functional cable is combined, to design, the production technology of cable, more stringent requirements are proposed, due to cable Power wire core ormal conductor section it is larger, and the conductors cross of control line and signal transmssion line then very little, in production process In be easy to be pulled, break；

3, very sensitive to extraneous interference in use process due to signal-transmitting cable, when in use power wire core and The electromagnetic field that extraneous cable generates easily generates interference to it, influences the normal use of signal-transmitting cable.

Utility model content
