Description

A kind of cold-resistant power cable of seabed special environment friendly height

Technical field

The utility model belongs to field of cable technology, and in particular to a kind of cold-resistant electricity of the dedicated environment-friendly type height in ocean seabed Power cable.

Background technique

Submarine cable is the seabed that is laid in, and the power supply systems such as development and utilization for marine energy are transported to electric energy transmission Product.In recent years, with the development that China's marine economy is built, the exploitation of offshore islands and marine energy is accelerated, seabed electricity Cable demand increasingly surges, between island, between island and city, offshore oil platform, deep sea energy source exploitation, Oversea wind hair Electricity etc. requires large batch of submarine cable.Existing submarine cable is also unable to satisfy sea in terms of waterproof, cold-resistant, tensile strength The requirement of bottom use environment.

Utility model content

The technical problem to be solved by the present invention is to provide a kind of cold-resistant electric power electricity of ocean seabed special environment friendly height Cable, compact-sized, waterproof performance is outstanding, and tensile strength is high.

In order to solve the above-mentioned technical problem, the utility model is accomplished by the following way:

A kind of cold-resistant power cable of seabed special environment friendly height, it is described exhausted including being twisted the cable core formed by insulated wire cores Edge core includes conductor, conductor shielding layer, insulating layer, insulation screen and copper strip shielding layer, and conductor screen is wherein extruded outside conductor Cover layer, the outer extruded insulation layer of conductor shield, the outer extruded insulation shielded layer of insulating layer, the wrapped copper strip shielding outside insulation screen Layer；Wrapped first blocks water wrapping layer outside the cable core, and first, which blocks water, extrudes waterproof inner cushion layer outside wrapping layer, twines outside waterproof inner cushion layer Around layer of steel wire armor, the outer winding steel wrapping layer of steel wire armor layer, wrapped second blocks water wrapping layer outside steel band wrapping layer, most Outer layer extrudes waterproof external sheath layer, blocks water wrapping layer first and copper strip shielding interlayer is also filled with flexible stretch-proof filled layer.

Further, the cable core is formed by 3 insulated wire cores are twisted.

The conductor is copper free wire circular copper conductors.

The waterproof external sheath layer protects jacket layer using the cold-resistant high density polyethylene (HDPE) of height.

Compared with prior art, the utility model has the advantages that

The utility model provides a kind of cold-resistant power cable of ocean seabed special environment friendly height, efficiently solves existing sea The problem of bottom cable is also unable to satisfy the requirement of seabed use environment in terms of waterproof, cold-resistant, tensile strength.

Specific embodiment

Specific embodiment of the present utility model is described in further detail in the following with reference to the drawings and specific embodiments.

The power cable as shown in Figure 1, a kind of seabed special environment friendly height resists cold, including by the twisted cable formed of insulated wire cores Core, the insulated wire cores include conductor 1, conductor shield 2, insulating layer 3, insulation screen 4 and copper strip shielding layer 5, wherein leading Conductor shield, the outer extruded insulation layer of conductor shield, the outer extruded insulation shielded layer of insulating layer, in insulation screen are extruded in vitro Outer wrapped copper strip shielding layer；Wrapped first blocks water wrapping layer 7 outside the cable core, and first, which blocks water, extrudes waterproof inner cushion layer outside wrapping layer 8, wind layer of steel wire armor 9 outside waterproof inner cushion layer, the outer winding steel wrapping layer 10 of steel wire armor layer, steel band wrapping layer it is outer around Packet second blocks water wrapping layer 11, and outermost layer extrudes waterproof external sheath layer 12, blocks water wrapping layer and copper strip shielding interlayer also first Fill flexible stretch-proof filled layer 6.

Power cable disclosed by the utility model, cable core are provided with waterproof layer outside, and steel wire armor layer is by more uniform rings Steel wire around arrangement forms, and blocks water second and is additionally provided with import height outside wrapping layer and resists cold high density polyethylene (HDPE) protection jacket layer, excellent Point is the cold-resistant power cable of the ocean seabed special environment friendly height, and low temperature resistant, waterproof performance is good, and tensile strength is high.

The above is only the embodiments of the present invention, is stated again, for the ordinary skill people of the art For member, without departing from the principle of this utility model, several improvement can also be carried out to the utility model, these improvement Also it is included in the protection scope of the utility model claims.
