Description
技术领域：Technical field:
本实用新型涉及电缆，尤其涉及一种四芯型监控组合电缆。 The utility model relates to cables, in particular to a four-core monitoring combined cable.
背景技术：Background technique:
耐火控制软电缆主要适用于各种火灾危险较大，消防安全重要性较高的电气装备及控制系统。 Fire-resistant control flexible cables are mainly suitable for various electrical equipment and control systems with high fire hazard and high importance of fire safety.
传统的耐火控制电缆制作工艺主要采用导体绕包云母带作为耐火层，从而起到耐火作用，但由于云母较脆，在绕包或转入下到工序时，可能出现云母脱落的现象，如果云母脱落严重，无疑在使用过程中，其耐火性能会大打折扣，安全性不能得到保障，且控制电缆一般芯数都较多，每根导体上都需要绕包，生产较麻烦。 The traditional production process of fire-resistant control cables mainly uses the mica tape wrapped around the conductor as the fire-resistant layer, so as to play a fire-resistant role. However, because the mica is relatively brittle, the mica may fall off when it is wrapped or transferred to the next process. If the mica The shedding is serious, no doubt during use, its fire resistance will be greatly reduced, the safety cannot be guaranteed, and the control cable generally has a large number of cores, each conductor needs to be wrapped, and the production is more troublesome. the
此外，传统的耐火控制电缆功能单一，不能起到监视的作用，因此，不能满足实际工作需求。 In addition, the traditional fire-resistant control cable has a single function and cannot play the role of monitoring, so it cannot meet the actual work requirements. the
实用新型内容：Utility model content:
为了弥补现有技术问题，本实用新型的目的是提供一种四芯型监控组合电缆，根据其使用场合环境对其结构进行了设计，其生产工艺简单，耐火性安全可靠，具有传输信号、监视的作用，满足用户使用要求。 In order to make up for the problems in the existing technology, the purpose of this utility model is to provide a four-core type monitoring combined cable, the structure of which is designed according to the environment of its use, the production process is simple, the fire resistance is safe and reliable, and it has transmission signal, monitoring role to meet user requirements.
本实用新型的技术方案如下： The technical scheme of the utility model is as follows:
四芯型监控组合电缆，包括数根导体，其特征在于：所述的数根导体外包裹有交联聚乙烯绝缘层构成绝缘线芯，绝缘线芯相互绞合成束构成缆芯，缆芯中心设有橡皮管，缆芯外依次挤塑成型有硅橡胶弹性层、陶瓷硅橡胶耐火层，陶瓷硅橡胶耐火层内设有监视线芯导体，监视线芯导体外依次耐高温聚酯带绕包构成的防火层、硅橡胶绝缘层，陶瓷硅橡胶耐火层外设有隔离层、低烟无卤聚烯烃护套层。 Four-core monitoring combined cable, including several conductors, is characterized in that: the several conductors are wrapped with cross-linked polyethylene insulating layer to form an insulated wire core, and the insulated wire cores are twisted together to form a cable core, and the center of the cable core There is a rubber tube, and the outside of the cable core is sequentially extruded with a silicone rubber elastic layer and a ceramic silicone rubber refractory layer. The ceramic silicone rubber refractory layer is equipped with a monitoring core conductor, and the monitoring core conductor is wrapped with a high temperature resistant polyester tape in sequence. Composed of a fireproof layer and a silicone rubber insulating layer, the ceramic silicone rubber refractory layer is provided with an isolation layer and a low-smoke halogen-free polyolefin sheath layer.
所述的四芯型监控组合电缆，其特征在于：所述的隔离层有高阻燃纤维带重叠绕包构成，绕包搭盖率不小于30%。 The four-core monitoring combined cable is characterized in that: the isolation layer is composed of overlapping wrapping of high flame-retardant fiber tapes, and the covering rate of the wrapping is not less than 30%. the
本实用新型的优点是： The utility model has the advantages of:
1、一改传统耐火电缆用绕包云母带作为耐火层的工艺，改为挤包陶瓷性硅橡胶作为耐火层，增加耐火可靠性及降低生产复杂性；电缆成缆后，不填充，不绕包，电缆圆整度高。 1. Change the process of wrapping mica tape as the refractory layer of traditional fire-resistant cables, and replace it with extruded ceramic silicone rubber as the refractory layer, which increases the reliability of fire resistance and reduces the complexity of production; after the cable is cabled, it does not need to be filled or wound Package, high cable roundness.
2、挤包陶瓷性硅橡胶耐火层后，再绕包一层高阻燃带，既作为隔离层使用，也起到阻燃作用，使电缆的阻燃耐火性能更好。 2. After the ceramic silicone rubber refractory layer is extruded, a layer of high flame-retardant tape is wrapped around it, which is used not only as an isolation layer, but also as a flame-retardant function, so that the flame-retardant and fire-resistant performance of the cable is better. the
3、将监视线芯和控制导体组合在一起，实现多功能的作用。 3. Combine the monitoring wire core and the control conductor to achieve multi-functional functions. the
