Abstract
The utility model relates to a 7 core watertight flexible cable is suitable for between submarine and the subsea equipment long distance control signal transmission and provides the electric energy. Include insulating core, gasket for packing, block water and glue, block water and take isolation layer and sheath, seven insulating cores strand the back with six roots of sensation gasket for packing packs the gluey I component cable core that blocks water in the gap, the cable core is equipped with two -layer blocking water outward in proper order and takes isolation layer and one deck sheath, the gluey II that blocks water is packed by stranded inner conductor hank and beam forming to the insulating core in the gap outside it, be equipped with the one deck insulating layer and constitute outside the gluey II that blocks water. Characteristics are: filling the glue that blocks water in stranded inner conductor gap and cable core gap, having played prevention water, gas passes through, has reached watertight, air -tight requirement, water inflation is by oneself met to this material simultaneously, further reaches the better effect that blocks water.
Description
Technical field
The utility model relates to a kind of 7 core watertight flexible cables, to be suitable between submarine and underwater installation long-distance control Signal transmissions and to provide electric energy.
Background technology
Common watertight cable generally adopts only son and heir's conductor, and whole cable is comparatively hard, and bending radius is large, is thus unfavorable for bending use.Flexible cable general is in addition applicable to mobile laying, and internal structure has activity space and remaining length, cannot meet watertight requirement, is not suitable for using under water.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provide a kind ofly have that softness, tensile strength are large, UV resistant, low temperature resistant and possess the one 7 core watertight flexible cable of features such as blocking water.
For achieving the above object, the scheme taked is the utility model: a kind of 7 core watertight flexible cables, is characterized in that: comprise insulating core, gasket for packing, the glue that blocks water, waterstop separator and sheath; Seven described insulating cores and six roots of sensation gasket for packing stranded after in gap, fill the glue I that blocks water form cable core, described cable core is provided with two-layer waterstop separator and one deck sheath outward successively; Described insulating core is twisted and bunchy by multiply inner wire, in the gap that it is outer, fill the glue II that blocks water, and is provided with one deck insulating barrier and forms blocking water outside glue II.
Feature of the present utility model is: inner wire is the tough copper conductor that resistivity is low, and to ensure the electrical property of conductor, guarantee that whole cable is soft, be easy to bending simultaneously and lay, inner wire adopts strands form processing.Insulating barrier adopts low cigarette, nontoxic polyethylene, and have excellent electric property, lower dielectric constant is the basic assurance of low decay, low electric capacity.The glue that blocks water adopts intumescent to block water room temperture rubber vulcanization, and this material at room temperature can short vulcanization solidifying, and is convenient to fill processing.Block water in multiply inner wire gap and cable core gap filling glue, serves and stop water, gas to pass through, reach watertight, airtight requirement, simultaneously this material meet water can self-expansion, reach better block-water effect further.Separator adopts the waterstop that expansion rate is high, water absorption rate is high, absorption speed is fast, positive and negative two-way wrapped with the rounding property requirement ensureing cable, plays again isolation and resistance effect simultaneously.Sheath have employed polyurethane elastomer, and it has low temperature resistant, the feature such as abrasion-resistant, hydrolysis, UV resistant, softness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model insulating core;
Fig. 3 is the structural representation of the utility model gasket for packing.
Embodiment
As shown in Figure 1, a kind of 7 core watertight flexible cables, comprise insulating core 1, gasket for packing 2, the glue 3 that blocks water, waterstop separator 4 and sheath 5.
Insulating core 1 is twisted and bunchy by multiply inner wire 1-1, multiply inner wire 1-1 twist and bunchy gap in filling to block water glue II1-2, extrude a layer insulating 1-3 outside glue II1-2 and form blocking water.
Cable core is formed by filling the glue I3 that blocks water after stranded to seven insulating cores 1 and six roots of sensation gasket for packing 2 in gap, at the outer just wrapped one deck waterstop separator 4 successively of cable core, back-roll bag one deck waterstop separator 4, finally outside two-layer waterstop separator 4, extrude one deck polyurethane elastomer sheathing 5.
Inner wire 1-1 is formed by strand copper wire system of twisting.
Insulating barrier 1-3 adopts polyethylene to melt extrude form.
Gasket for packing 2 is by aramid fiber yarn 2-1 and water blocking yarn 2-2 is stranded forms.
Block water glue I3, the glue II1-2 that blocks water is intumescent and blocks water room temperture rubber vulcanization.
