Feature:

1,it has characteristic of strong moisture absorption,big expansion rate and quick expansion velocity.

2,small resistance can make cable has semi-conductivity and weaken the electrical field strength effectively.

3,high mechanical strength makes it easy to be wrapped and longitudinal wrapped for kinds of cables.

4,it is heat-resistant and can bear high instant temperature.cable with this product can keep stable performance at instant high temperature.

Storage:

it should be stored in dry house,kept away from source of fire and not to be exposed to the sunshine.the shelf life is 6 months after the manufacturing date.also it should avoid moisture and mechanical damage during storage and transportation.

Q: Apple phone display cable or accessories not certified how to do: The control cable transfers the electrical energy from the power distribution point to the power supply lines of the various electrical equipment The rated voltage of the power cable is generally 06 / 1kV and above, the control cable is mainly 450 / 750V The same specifications of the power cable and control cable in the production, the power cable insulation and sheath thickness than the control cable thick

Q: What machinery is required to make wire and cable?: Pouring concrete when you can line? Do you clear the problem?

Q: Ipad not charge how the matter. Said the cable or accessories have not been certified, and may not be able to cooperate with this ipad reliable work....: Then you get the repair station to see what is the problem

Q: IPadmini. The latest version 7.1.1 up in the morning to see the non-stop display this cable is not certified does not support this feature. The The Charger original. Not on the computer charge. The Ask God to answer more: Data line problem, it may be the data line to the bad, caused by poor contact. For the sake of the root

Q: Apple mobile phone does not support this charge when charging this thing how to charge: Charging line and the phone does not match, for the good point of the line just fine

Q: Apple 6 Charging Why always show this cable has not yet been certified: And I answered the other person's question is very similar: . the line of the banding distance of not more than 1.2 meters, the two ends of the wire box outlet tube 15CM should be ligation; . casing embedded, then through the basement wall, the surface must be installed rigid Waterproof casing, that is, steel pipe + water ring; through the fire pool, living pool: flexible waterproof casing; (wing ring specific practices can be collected online related Atlas); through the floor, according to whether the design requirements , Under normal circumstances PVC casing on it. Note: . rigid waterproof casing, flexible waterproof casing is a one-time reserved in place, through the floor of the casing of the flower lamb to suppress the barge of Xi Jie Xi Xi shou, is the first stay hole, when the installation of riser Casing, because the floor casing has every layer, the location of the reservation will always be biased, in order to ensure vertical vertical pipe, and finally unified hanging line repair hole and then install the riser and casing. . now most of the bathroom are dirty, waste and diversion, and more of the riser, and so on, the air conditioning casing of all the shear wall should be embedded, to avoid the subsequent damage to the structure of drilling (no stay can only drill) Note that the location of the hole and the installation of the riser will affect the opening of the toilet window. . the casing is the casing, riser is the riser, casing than the riser model 1 to 2 level. . plate at the end of flat, board 2 to 5CM higher to see if you need to do leveling layer.

Q: Why does the bird stand on the wire without anything, but if people touch it,: Is not the home of the bus box? Generally put a cat, a router, a power outlet, two transformers, the other is the network cable and telephone, the key space to be enough

Q: How are various wire and cable models named?: Cable type a lot, here to give an example: ZRC-YJV22-0.6 / 1KV3 * 25 +2 * 16 This model specification means: C-class flame retardant (ZRC) XLPE insulated (YJ) PVC jacket 22) steel tape armor (0.6 / 1KV) 0.6 / 1 kV (3 * 25) 3 25 square (+ 1 * 16) plus two 16 square copper conductor flame retardant copper core steel tape armored cross-linked poly Ethylene insulated PVC sheathed low voltage electric power.

Q: What are the T and T, s of the wire and cable test type?: The expression is not very clear, it should be said to wear a tube, if a single wear on the line 100. Outside diameter 60mm.

Q: What is the warranty period for wire and cable?: Wire and cable warranty period is 30 years of national warranty period. But the specific warranty period according to the type of wire and cable and the use of conditions and temperature and applicable methods to determine. General cable maintenance period is about 15 years, but to ensure that the normal use of the environment, such as the amount of temperature is below 70 degrees, but you are more than 70 working environment to use, of course, may not be used for a year. Therefore, the most important thing is to follow the instructions to use.
