电缆地线芯绝缘采用具有抗氧化性能的K型B类低密度聚乙烯。
聚乙烯的绝缘电阻高，耐电压好，介电系数小和介质损耗温度和变频率的影响也小，不但能满足传输性能的要求，能确保电缆的使用寿命。
为了减少回路间的相互串扰和外部干扰，电缆采用屏蔽结构。

井道在各楼层设有门厅及呼梯设备。
门厅有门厅门，厅门顶部装有楼层指示灯，用于指示电梯的运行方向及电梯所在的位置。
门厅里还设有呼梯盒，用于在每层站召唤电梯。
呼梯盒常安装在厅门外离地面1m左右的墙壁上，基站与顶站的呼梯盒上只有一个按钮，中间层站的呼梯盒上有上呼和下呼两个按钮，按钮下带有呼梯记忆灯。
基站的呼梯盒上还设有钥匙开关，供司机开关电梯。
为了实现轿厢的正常运行及准确停车，井道中往往要安装许多定位装置及安全设备。
●电缆的最低敷设温度:0℃。
低于最低敷设温度时应预热。
(3)电缆线芯与线芯及线芯与屏蔽间通过交流2500V/5min电压试验。

Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyethylene or polyvinyl chloride thin sheath. Sheath thickness may depend on the basic cable outer diameter. 4, identification and marking: cable appearance with permanent identification mark, tag, at no more than alternate 1 m intervals between 5, sheathed communication cable tag contents are: the diameter of wire, wire on the , type of cable, length, factory name and year of manufacture. 6. Armored communication cable electrical characteristics: the cable meets all the electrical re of the basic cable. 7. Cable length: mechanically protected cable is manufactured according to the standard length of the corresponding basic cable
Crane or forklift should be used for the loading and unloading of cables. It is forbidden to run flat or lay flat. For installation of large cables, cable laying cart should be used to avoid external damage or abrasion caused by manual dragging. If the cable cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight from exploding and water entering the end of the cable. Note: the installation of wire and cable should be familiar with the performance of wire and cable installation personnel or full-time technical personnel, if there are still unclear matters, ball related technical department or technical department of our factory.
2:配管工艺：要注意的是线管要转大弯活弯，因地适时采用点对点的施工工艺为过后穿线铺垫好基础。
在接头处先用胶水密封再用铁丝扎实。
3:预埋后续检查，加固。
对每个点位按照图片再仔细检查一遍，有没有漏掉的点位及时修改。
再接头的地方用扎丝加固。
防止打混泥土的时候打掉。
对一些多余的管通进行堵塞密封,防止堵塞。
三：排水、粪水预埋：可以按照污水，粪水，排气三个管路。
