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: What machinery is required to make wire and cable?: Pouring concrete when you can line? Do you clear 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: The problem lies in the charger between the machine, IPAD charging is to a charging protocol to complete, when the IPAD did not receive the agreement signal will be prompted: do not support this accessory, Apple's products have charging protocol, charging Is through the data line in the two lines and IPAD transmission charging protocol signal when ipad received the charging protocol signal after the machine internal charging circuit began to open the internal charging circuit to charge, the problem is to accept the charge signal is not so prompted not to Support, change the line to try

Q: Do not know why not mislead. The The The The The Fire resistance is IECGBBS6387. GB is the general principle of flame retardant and fire resistant wire and cable, quoted the above criteria...........................: I think it is possible, because in our (old) substation, the cable trench is the drain, the cable erected in the cable bracket.

Q: Apple mobile phone does not support this charge when charging this thing how to charge: Just show that the sound is still in the host, must be an external sound, your computer monitor can sound it? Not to sound - Bao Haiping studio

Q: Decoration when the purchase of water pipes, wires and other items included in the account: Outdoor fire line must use fire-resistant KVV cable, wear pipe protection.

Q: What is the difference between "wire" and "cable"?: Simple point, the plotter is generally used to out of the line map, the general is the Academy of Engineering, the Bureau of the use of a CAD map, and some can also be some effect of the general effect of the map, generally suitable for color requirements are not very high, but right Print accuracy requires a high place. Inkjet machine can be divided into indoor and outdoor ink, outdoor irritating smell, for outdoor advertising like the effect of the map, the indoor no irritating smell, the general subway, as well as other indoor advertising are used this out of

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: What are the varieties of wire and cable (detailed point): The meaning of the letter: W refers to the halogen-free, D refers to the low smoke, Z refers to the flame retardant WDZ is halogen-free low smoke flame retardant jacket power cable. WDZC refers to halogen-free low smoke C-class flame retardant

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: If you want to sell wire and cable, then what to do in advance to detect? The The The The The: To be considered is the Great Wall power line is not long enough, the power is not big enough to see the power on the label, if the 12V to 15A or more I think will be more stable, my Dell machine power cord surprisingly short, but also To buy the extension line again.
