Flame-retardant cables are characterized by a delay in the spread of flame along the cable so that the fire does not expand. Because of its low cost, it is a kind of cable widely used in fireproof cable. Under the condition of single cable or into a bunch of laying, cable to know when the spread of flame can be controlled within a certain range, so it can avoid fire spreading combustion and lining major disasters, which cable line of fire prevention level.

In flame retardant series products, has been successfully used in the oxygen isolation technology, not only 0.6/1 kv polyvinyl chloride insulated and crosslinked polyethylene insulation flame retardant power cable can achieve GB/T12666.5 "into A bunch of power cable test" in class A, and rated voltage up to and including 6/10 kv 6/10 kv crosslinked poly (flame retardant power cable can reach A high class A demand and A large margin. On the basis of high flame retardant and high flame retardant cross-linked insulation, a low-smoke halogen-free high-flame retardant oxygen insulation layer power cable was added, and its low-smoke halogen-free performance was in line with GB/T17651.1.2 and GB/ t1765650.1.2. In this way, the overall level of the company's cross-linked power cable is lower than the domestic status.

如果有两根线能够点亮电笔，则证明电路为直流电。方法2：当线路中为交流电时，电笔的亮度较高。当线路中为直流电时，电笔的亮度较低。方法3：观察电笔的发光位置。同样是用电笔接触火线，如果是直流电，电笔内部的氖泡只在一端发光；如果是交流电，电笔的氖泡会整根亮起。电笔中的氖泡区分正负极通过观察氖泡的发光位置，还能够同时知道直流电的正负极。上文说到，直流电中，氖泡只在一端发光。如果氖泡是在笔尖一端发光，则所测位置为电源正极；反之，为电源负极。
