Description

一种铜丝钢丝混合编织屏蔽铠装电缆Copper wire steel wire mixed braid shielded armored cable 技术领域Technical field
本实用新型涉及一种电缆，具体是一种铜丝钢丝混合编织屏蔽铠装电缆，属于电缆制造技术领域。The utility model relates to a cable, in particular to a copper wire steel wire mixed braided shielded armored cable, which belongs to the technical field of cable manufacturing.
背景技术Background technique
铜丝编织屏蔽钢丝铠装电缆多采用独立的铜丝编织层、独立绕包或挤出的内衬层、独立的钢丝铠装层，铜丝编织层具有良好的屏蔽效果，钢丝铠装层具有优异的抗拉效果。如授权公告号为CN206976043U的专利文献公开了了一种钢丝铠装光电复合测井缆线，耐高温光纤和耐高温填充物置于中心不锈钢管内，中心不锈钢管外有铜丝编织，铜丝编织被耐高温绝缘层挤包，耐高温绝缘层置于外不锈钢管内，外不锈钢管外铠装有内层镀锌钢丝和外层镀锌钢丝。The copper wire braided shielded steel wire armored cable mostly uses an independent copper wire braided layer, an independently wrapped or extruded inner lining layer, and an independent steel wire armored layer. The copper wire braided layer has a good shielding effect, and the steel wire armored layer has Excellent tensile effect. For example, the patent document with authorization announcement number CN206976043U discloses a steel wire armored optoelectronic composite logging cable. The high temperature resistant optical fiber and the high temperature resistant filler are placed in the center stainless steel tube, and the center stainless steel tube is braided with copper wire, and the copper wire braid is The high-temperature-resistant insulating layer is extruded, and the high-temperature-resistant insulating layer is placed in an outer stainless steel tube, and the outer armor of the outer stainless steel tube is equipped with an inner galvanized steel wire and an outer galvanized steel wire.
但是，这类铜丝编织屏蔽钢丝铠装电缆虽然达到了屏蔽和抗拉的效果，但是电缆成本相对较高，外径过大，弯曲性能差，致使仪表控制电缆在敷设过程中有诸多不便。However, although this type of copper wire braided shielded steel wire armored cable has achieved the effects of shielding and tensile strength, the cable cost is relatively high, the outer diameter is too large, and the bending performance is poor, which causes many inconveniences in the laying of the instrument control cable.
实用新型内容Utility model content
本实用新型的目的是提供一种铜丝钢丝混合编织屏蔽铠装电缆，该电缆降低电缆成本，保证了优异弯曲性能的同时，也最大限度的降低了电缆外径，使敷设简单化。The purpose of the utility model is to provide a copper wire steel wire mixed braided shielded armored cable, which reduces the cable cost, guarantees excellent bending performance, and also reduces the outer diameter of the cable to the greatest extent, simplifying the laying.
为了达到上述技术目的，本实用新型的技术方案是：In order to achieve the above technical purpose, the technical solution of the present invention is:
一种铜丝钢丝混合编织屏蔽铠装电缆，其包括成缆缆芯，所述缆芯外设置有编织层，所述编织层采用钢丝与铜丝混合编织，所述编织层外设置有护层。A copper wire steel wire mixed braided shielded armored cable includes a cable core, a braided layer is arranged outside the cable core, the braided layer is mixedly braided with steel wire and copper wire, and a protective layer is arranged outside the braided layer .
所述缆芯与编织层之间绕包有包带，具体地，所述包带为单面铝箔，所述单面铝箔的铝面朝向编织层。A wrapping tape is wrapped between the cable core and the braided layer. Specifically, the wrapping tape is a single-sided aluminum foil, and the aluminum surface of the single-sided aluminum foil faces the braided layer.
为了在获得优异的屏蔽性能的同时，最大程度保证屏蔽的连续性，所述编织层的编织密度≥90％。In order to obtain excellent shielding performance while ensuring maximum continuity of shielding, the braided density of the braided layer is ≥90%.
电缆外径：Cable outer diameter:
常规结构因具有屏蔽、内衬、铠装三层结构，外径较大，敷设不便。本实用新型结构采用钢丝铜丝混合编织，将铠装结构与屏蔽结构结合在一起，同时去掉了内衬层，很好的减小电缆外径。The conventional structure has a three-layer structure of shielding, lining and armor, and has a large outer diameter, which is inconvenient for laying. The structure of the utility model adopts mixed braiding of steel wire and copper wire, combines the armor structure and the shield structure, and simultaneously removes the inner lining layer, which reduces the outer diameter of the cable well.
电缆成本：Cable cost:
常规结构具有内衬、屏蔽和铠装三层结构，成本较高。本实用新型结构只用一层钢丝与铜丝的混合编织结构，取代了常规的三层结构，大大降低成本。The conventional structure has a three-layer structure of inner lining, shielding and armor, and the cost is higher. The structure of the utility model only uses a mixed braided structure of one layer of steel wire and copper wire, which replaces the conventional three-layer structure, which greatly reduces the cost.
生产效率：Productivity:
常规结构共有三道工序，生产工序越多，产品越容易出现问题，且生产速度低。本实用新型结构只有一道工序，提高了生产效率，降低了生产风险。There are three processes in the conventional structure. The more production processes, the easier the product is to have problems and the production speed is low. The structure of the utility model has only one process, which improves the production efficiency and reduces the production risk.
弯曲性能：Bending performance:
常规的多层结构以及斜包的钢丝均影响了电缆的弯曲性能。本实用新型的钢丝与铜丝采用了混合编织，弯曲性能优异。The conventional multi-layer structure and obliquely wrapped steel wire both affect the bending performance of the cable. The steel wire and the copper wire of the utility model adopt mixed braiding, and the bending performance is excellent.

本实用新型的电缆，编织结构中的材料铜丝和钢丝比重均为1/2，为了保证屏蔽性能和抗拉效果，编织密度最小为90％，编织层下面绕包一层单面铝箔，以此替代目前电缆行业采用的独立屏蔽层-独立内衬层-独立铠装层的常规结构。In the cable of the utility model, the specific gravity of the copper wire and the steel wire in the braided structure are both 1/2. In order to ensure the shielding performance and the tensile effect, the braided density is at least 90%, and a single-sided aluminum foil is wrapped under the braided layer. This replaces the conventional structure of independent shielding layer-independent inner liner-independent armor layer currently used in the cable industry.
本实用新型采用了一种铜丝与钢丝混合编织的结构，有效的替代了常规结构，去除了内衬层，降低电缆成本，保证了优异弯曲性能的同时，也最大限度的降低了电缆外径，使敷设简单化。编织+单面铝箔的双重屏蔽结构提供了优异的屏蔽性能的同时，也最大程度保证了屏蔽的连续性。铜丝钢丝混合编织提供了良好的抗拉性能。The utility model adopts a copper wire and steel wire mixed braided structure, which effectively replaces the conventional structure, removes the inner lining layer, reduces the cost of the cable, and ensures the excellent bending performance, while also reducing the outer diameter of the cable to the maximum To simplify laying. The double shielding structure of braided + single-sided aluminum foil provides excellent shielding performance while also ensuring maximum shielding continuity. Copper wire steel wire mixed braiding provides good tensile properties.
