售后服务是全屋定制的诚信保证在一次定制家居产品售后服务调查中,有37%受访者表示需要品牌售后服务,有近7%受访者则认为买家居得先看其售后服务记录。部分消费者表示,其因在于定制产品普遍在丈量尺寸、给出设计方案、出图之后便要求付全款,付款之后店家才会给工厂下单,消费者怕付全款之后,一旦买家违约或者拖沓,将很难进行维权。如何增加消费者的安全感,定制经销商回应:客户下订单以后,需要派出设计师上门量尺,出设计稿,下单给工厂,整个过程都需要付出成本,一旦客户退单,我们将无法二次销售,因此需要下订金,确定设计图纸后付全款。

Precautions for installation of power cables: keep 2m distance when the cable is installed in parallel with the thermal pipe, and 0.5m should be maintained when crossing. The cable shall be installed at a distance of 0.5m in parallel or across other pipelines. When the cable is directly buried and installed, the direct buried depth of 1-35kv cable is less than 0.7m. When 10KV and below cables are installed in parallel, the net distance between them shall not be less than 0.1m and 10-35kv shall not be less than 0.25m. The distance of cross installation is not less than 0.5m. Cable laying temperature lower than 0 ℃, bending radius: multi-core cable or 15 (D + D), a single cable 20 or more (D + D), (D for cable diameter, D) for the conductor diameter. ? 6KV and above cable connector:? When installing the terminal head of the cable, the semiconductor electrical shielding layer must be stripped off. During operation, the insulation shall not be damaged. The shield end should be flat and the graphite layer (carbon particles) should be clean. (2) plastic cable end copper tape screened and armor must be good grounding, the short circuit also follow this principle, oid unbalanced three-phase run ShiGang armoured end produce inductive electromotive force, and even "lighter" and sheath and other accidents. It is required to use my tinplate to braid copper wire for grounding lead. When connecting with the cable copper belt, it should be welded with chromium-iron tin. ? The shield of three-phase copper tape should be connected with ground wire respectively. Note that the shielded ground wire and steel armor ground wire should be separately drawn out and insulated from each other. The position of the welded ground wire should be as low as possible. Basic requirements for cable terminals and intermediate joints: a. good conductor connection; B. The insulation is reliable, and it is recommended to use irradiated cross-linked heat-shrinkable silicone rubber insulation materials; C. good sealing; D. sufficient mechanical strength to meet various operating conditions. The end of the cable must be used to prevent water and other corrosive materials from corroding, in order to prevent the water tree caused by the aging of the insulation layer and breakdown. 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 oid 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.

电缆的要求是根据不同场合分别采用:对绞组合、对绞组成电缆的总、对绞组合后总等方法。材料有圆铜线,铜带、铝带/塑料复合带三种。对与对具有较好的绝缘性能,电缆在使用中若对对之间出现电位差时,不会影响信号的传输质量。
Steel tape armoured mainly as the radial mechanical protection layer of the cable, and it also he additional total shielding effect, especially steel tape armoured and copper wire, copper tape screened, is adopted two different shielding materials, play a complementary role in electromagnetic we shielding, shielding effect will be better.
因为经过较长时间后,各连接点产生氧化,锈蚀等情况会使仪表实际上不起作用。防晒:应避免阳光直射在仪表黑色外壳上,否则有可能会使仪表工作环境超过额定温度范围而损坏。防水:一般情况下,仪表工作环境的湿度虽可达95%,但都规定不能产生结露。特殊的具有防水功能的不锈钢外壳仪表除外。防腐:腐蚀性物质不能渗进仪表内部,否则会对线路板上的器件和线路板本身产生腐蚀,时间一长,可能会使仪表报废。即使是具有防腐功能的仪表,如果封闭不严,也会有同样的结果。防雷击:电子衡器属于弱电系统,容易受到雷电的袭击而损坏部件。雷电主要从两个方面进入仪表:由电源线导入和由秤台经信号缆导入。在正常天气下,操作人员只要操纵电源开关即可,但在可能发生近距离雷击的情况下,必须拔下仪表电源插头及秤台信号电缆插头。采取防雷击措施,在仪表电源回路中增加防浪涌保护器等。防强电:22伏以上的电源火线意外地搭到秤台或利用秤台作地线,在秤台上进行电焊操作都有可能损坏仪表。清洁:在工业环境下,仪表外壳上会有积灰或受到污染,必须在断电情况下经常用湿抹布擦干净。但要注意不能用酒精等溶剂擦拭显示窗,这样会使透光性能变坏,显示模煳不清。.防静电:一旦仪表损坏,就要送修。有的单位为了使来回传递的速度加快,喜欢把仪表的PCB板拆下来,用特快专递邮寄,这就产生一防静电的问题。取PCB板时要手持板的四角,切勿用手摸到有集成块引脚的地方。因为这样容易让静坏集成块。拆下的PCB板应立即装入袋,在没有袋的情况下可用普通报纸包好。
