For cables with armor,it should be no less than 6 times of external diameter of cable.
For cables with armor or copper tape screen,it should be no less than 12 times of external diameter
of cable.
For flexible cables with screen,it should be no less than 6 times of external diameter of cable.
Zero halogen characteristics:

- Q:I see a lot of lights are installed in the green belt on the side of the road, buried when the armored cable is also used without armor. I would like to ask if the water in the green belt does not affect the insulation of the cable should choose what type of cable. What circumstances to use armor what circumstances do not armor. YJV.VV and other models of the power cable can be waterproof or moisture it? Please understand the master who speak, thank you. More
- First, the choice of wire and cable models When using wire and cable, to consider the use, laying conditions and safety; For example, depending on the use of different power cables, overhead insulated cables, control cables, etc .; depending on the laying of different conditions, General plastic insulated cable, steel armored cable, steel armored cable, anti-corrosion cable, etc .; according to safety requirements, can choose non-flame retardant cable, flame retardant cable, halogen-free flame retardant cable, fire-resistant cable. Second, the choice of wire and cable specifications to determine the use of wire and cable specifications (conductor cross-section), the general should consider the heat, voltage loss, economic current density, mechanical strength and other selection conditions. According to experience, low-voltage power line because of its large load current, it is generally selected according to the heat conditions, cross-section, and then check the voltage loss and mechanical strength; low-voltage lighting line because of its higher voltage level, the first voltage loss conditions Select the cross-section, and then check the heat conditions and mechanical strength; for high-voltage lines, the first by the economic current density selection section, and then check the heat conditions and allow the voltage loss; and high-voltage overhead lines, but also check its mechanical strength. If the user has no experience, should consult the relevant professional units or people's views.

- I like to have childhood education puppies, every time there is a sense of accomplishment. But the landlord, we must have patience, my dog ??is also full moon to take home, four or five days to learn to go out at night when the lights back to sleep, pull urine know the toilet. Talk about my method Every day I will lead the little guy to the toilet more than 20 times, really, if he pulls urine in the toilet, then you must praise to his favorite play, or like to eat things, my dog ??dog Three days to know the toilet, but at night or near the house pull urine. To the fifth day even at night, the little guy will go to the toilet nn. Must be diligent little, led him to the toilet. And then there is the dog to sleep, he is not pull the urine, so if he sleep in the toilet, it will not be convenient in the toilet. It is recommended to let the little guy in the house to sleep, develop habits. But can not arm around sleep, my home dog's first day to let him sleep in the kennel, although called a night, but the next day is clearly not so called, the third day to hum a For a while, to the fourth day of their own in the nest to sleep. Puppy from an early age to develop an independent, toilet wet, long time off, easy to make the dog's joints problems, serious, may be paralyzed. Of course, can take a bath, but must be dry, otherwise it is easy to skin disease, when it is not easy to treat.

- Q:"Power engineering cable design specifications" 5.1.3 provides: cable group installed in the same channel in the same side of the multi-layer bracket should be arranged according to the voltage level from high to low power cables, strong to weak control and signal cables, The order of the communication cables. Ask the different levels of cable laying, why high-voltage cable laying in the upper? Ask the big god Q & A! More
- Such as lightning rod cited as a line, you can use single-core high-voltage cable, you can also set the metal pipe laying! The reason is simple: lightning is static, not alternating current! Only AC can pass through the capacitance between the cable core conductor and the metal tube! Therefore, the transmission of AC power is not allowed to use a single core armored cable or wear pipe laying!

In the custom cable is, if it is their own home, it is best to tell the manufacturer, you need to bring up the power, so that they come to you choose the model specifications, they will be selected according to their own standards, To ensure the normal use of the cable, if their own calculations, the factory may not be required after the loss of the requirements; design institute design, you can directly tell the factory specifications model. Mainly to see whether the cable head rust, shape is rounded, the entire thickness is uniform. Other you do not have the amount, and basically can not meet the national security standards.
- Q:i have a cable box in my living room and its hooked up to my tv but i still want to connect it to my projector and my projector has a usb type b input can i connect my cable box to my projector
- Depending on the specific model of your Projector, you can either have S video, RCA, VGA or a few other choices of INput connection. Depending on your cable provider and hookup, you can either have a plain cable with F connector or a cable box normally with RCA connectors and a remote control. If you have a simple cable connection that attaches direct to a TV (no remote, no box), you would need a TV Tuner to be able to receive the different channels whose output would be a composite video signal into the yellow RCA jack. You would need an RCA to RCA cable to in turn connect it to your Yellow RCA Video INput of the projector. In the absence of a tuner, an old VCR with such a feature would also serve the purpose. In some instances either units may also have an S video connection. If you have a cable box with with remote, then there is no need for a tuner or VCR since its output would already match the projector's input. Either way you would need a separate audio amplifier/speaker for the sound. Hope this be of some help/idea. Pls post back how things turns up or should you need additional information. Good luck and kind regards.
