Flame retardant cables and fireproof cables: the difference between the average person is very easy to confuse the concept of flame retardant cables and fireproof cables, although there are many more flame retardant cable applies to the advantages of chemical enterprise, such as low, low smoke, non-halogen, but in general, fire-resistant cable can replace flame retardant cable, and flame retardant cables can't take place of fire-resistant cable.
买房对于普通百姓来说是一生中的大事。
买房涉及到很多方面，那个方面考虑不周，都可能会给今后入住带来隐患。
目前买房者往往关注的地段、户型、价格等直观因素，从而忽略了许多安全因素。
比如，住宅内的电气线路容易被忽略。
其实，电气线路的可靠性与日常生活用电息息相关，如果电气线路选择不合适，轻则引起频繁跳闸，重则引发电气火灾或人身电击伤亡事故。
住宅电气线路属于隐蔽工程，线路采用暗埋法，日后发现问题而对线路进行改造时，费工、费时、费钱。
This product is suitable for electronic computers with rated voltage of 500V and cables with high re of anti-interference. Type K B low density polyethylene with anti-oxidation property is adopted for insulation of cable core. Polyethylene high insulation resistance, good resistance to voltage, small dielectric coefficient and temperature and the influence of variable frequency dielectric loss is small, can not only meet the res of transmission performance, and can ensure the service life of the cable. In order to reduce crosstalk and external interference between circuits, the cable adopts shielding structure. The shielding res of cables are respectively adopted according to different situations, such as the method of shielding the hinged combination, the method of shielding the hinged combination, and the method of shielding the hinged combination after the hinged combination. Shielding materials are round copper wire, copper belt, aluminum belt/plastic composite belt three. Shielding pair and shielding pair have good insulation performance. If there is potential difference between shielding pair and shielding pair, the signal transmission will not be affected.

一个家居装修的好不好，不仅仅是好看，更重要的还是内在，“外强中干”的房屋，我们可不能要。
其中“内在”中最为重要的，大概就当属水电装修了。
水电装修的好坏直接关系到我们以后生活质量的好坏，不要只关注家装效果图也要看家装水电图纸。
下面我们通过一些家装水电图纸来详细了解一些水电装修中的重要事项。
什么是家装水电施工图？家装水电施工图，是家居的水路、电气施工的前题与依据，它以施工人员都看得懂的符号标注在施工图纸上，来指导工人进行相应的作业。
