Description

[Technical field]

[0001] The utility model relates to the technical field of network cables, in particular to the technical field of oil-filled excellent waterproof UTP CAT6 network cables adopting a skin-foam-skin four-layer co-extrusion technology. [Background technology]

[0002] CAT6 UTP structure network cable is a very common product. The middle cable core is equipped with a cross frame, the core wire is insulated, and the sheath material is a non-shielded structure. There is no metal shielding layer to block it, which is very easy to be penetrated by water, resulting in poor water blocking effect. Domestic outdoor network cables generally use PVC+PE double sheath solution to achieve better water blocking performance, which greatly increases the overall cost and lacks market competitiveness. [Contents of the utility model]

[0003] The purpose of the utility model is to solve the problems in the prior art, and proposes an oil-filled excellent waterproof UTP CAT6 network cable using the skin-foam-skin four-layer co-extrusion technology, which can greatly reduce the dielectric constant of the insulation to achieve the effect of improving the propagation delay and increasing the transmission speed. A linear low-density PE material is used as the sheath, and a low-dielectric constant ointment is added to the material, which is non-hydrophilic and has water-separation properties to prevent water penetration. The use of linear high-density PE has excellent water-blocking performance.

[0004] To achieve the above-mentioned purpose, the utility model proposes an oil-filled excellent waterproof UTP CAT6 network cable adopting the skin-foam-skin four-layer co-extrusion technology, comprising a conductor core, a high-density PE sheath, a foamed insulating sheath, an inner insulating sheath, a linear PE outer sheath, and a low dielectric constant grease layer. The outer side of the conductor core is provided with a high-density PE sheath, the outer side of the high-density PE sheath is provided with a foamed insulating sheath, the outer side of the foamed insulating sheath is provided with an inner insulating sheath, the outer side of the inner insulating sheath is provided with a linear PE sheath, and a low dielectric constant grease layer is filled between the inner insulating sheath and the linear PE outer sheath.

[0005] Preferably, the conductor core is a solid conductor wire.

[0006] Preferably, the high-density PE sheath is tightly wrapped around the outside of the conductor core.

[0007] Preferably, the foamed insulating sheath is a skin-foam-skin physical foamed sheath, and the foaming degree of the foamed insulating sheath is above 60%.

[0008] Preferably, the inner insulating sheath and the linear PE outer sheath are bonded together.

[0009] Preferably, the linear PE outer sheath is a linear low-density PE sheath.

[0010] Preferably, the foamed insulating sheath is a low-density PE sheath.

[0011] The beneficial effects of the utility model: the utility model combines the conductor core, high-density PE sheath, foamed insulation sheath, inner insulation sheath, linear PE outer sheath and low dielectric constant ointment layer together, and after experimental optimization, adopts the skin-foam-skin physical foaming technology, which can greatly reduce the dielectric constant of insulation, thereby achieving the effect of improving propagation delay and increasing the transmission speed. Linear low-density PE material is used as the sheath, and low dielectric constant ointment is added to the material, which is non-hydrophilic and has water-separation properties to prevent water penetration. Linear high-density PE is used to make the water-blocking performance excellent. The skin-foam-skin physical foaming technology is adopted, and the foaming degree reaches 60%. After the foamed insulation is adopted, the dielectric constant of the insulation can be greatly reduced, thereby achieving the effect of improving propagation delay and increasing the transmission speed.
