Product Description:

I. Characteristics of the cables
1. Using factory prefabrication methods can substantially reduce the site construction labor intensity and shorten the construction laying time;
2. Use of cables can guarantee great length and bending property, and greatly facilitates the construction in a complex place;
3. Use of cables reduces the laying space, and cables can be installed together with gas and hydraulic gas pipelines;
4. Their reliability and reliability can be fully guaranteed, for the cables are manufactured in the factory,
5. Sub-branch parts should use high strength sealed joints, which are waterproof and have properties of moisture protection, long-term maintenance and free for repair;
6. Because the cables are directly connected with households with no need of maintenance and repair and with easy and simple construction, the cables can produce significant comprehensive economic benefits.
II. Usage of the cables:
1. To be used for high-rise building;
2. To be used for disaster prevention equipments;
3. To be used for tunnel lighting and disaster prevention equipments;
4. To replace copper bus bar with small or medium capacity in various places.
III. Standards of the cables
IEC 60502 Rated Voltage 1 ~ 30KV extruded insulated power cables and accessories (International Electrotechnical Commission standards)
GB 12706 Rated voltage 35KV and below Copper core, Aluminum core plastic insulated power cable (National Standard of the People's Republic of China)
JCS 376 branch cable (Japanese Electric Wire Industry Standard)
General Rules for JIS C2810 indoor wiring electrical connection pipes (Japanese Industrial Standard)

Types of the cables:
Standard main cables and branch cables are all low-voltage power cables with XLPE or PVC insulation materials (IEC, GB, JIS, BS ... ...), and PVC materials covered on the outer side. Generally, the main cable is single-core or twisted multi-core cable (cables with two to five cores), the branch cables are single-core cables, and may adopt a fire-resistant, flame retardant cables in accordance with the requirements.
Their structures and types are as follows:
No.

Q:what are the power requirments of 7950gt graphics card?
The psu in your pc will need to be supplying between 450 and 500 watts.
Q:"Cable laying" cable cross-sectional area refers to the cable cross-sectional area, or refers to the copper core cross-sectional area
YJV22 indicates "copper core XLPE insulated, steel tape armored PVC sheathed power cable" 0.6 / 1KV indicates its pressure rating, 5 * 10 represents the cross-sectional area of each wire diameter Is square mm, referred to as the square, the diameter of the conversion is 4.05
Q:Apple mobile phone does not support this charge when charging this thing how to charge
This is mainly to see the tube with a wire, or directly laying in the wall. If the pipe is used BV-type single-layer insulated wire, because it is not required to wear pipe jacket. Such as the direct laying in the wall with BVVB type wire (two wire core, insulation plus jacket) is better, the sheath can protect the wire from external damage.
Q:no any power cable for my new graphic card.plzzz help?
This is something you should check before you buy the video card. The card may have come with an adapter that plugs into a couple of your ide molex power connectors, and has the 6 pin connector you need on the other side. That might do it for you. Unless you don't have ide power connectors either. Or you can buy a new power supply. If your current power supply isn't big enough to support the new card you may end up buying a new power supply anyway.
Q:where can i put my amp power cable through my bulk head in my 1999 ford mondeo?
Find the main harness going through the fire wall and follow it
Q:ATX Power Supply/Cables?
Unless you have a good reason for putting it there and plenty of air flow the bottom of the case is not a good place to put a power supply. They generate a lot of heat and this will rise up into the case.
Q:Can you plug a power supply 6 pin cable into a 4 pit motherboard slot?
No, okorder.com. I know they have extensions so they should have what you are looking for.
Q:Power cable YJV22-8.7 / 15kv-3 * 300 what meaning
Power cable YJV22-8.7 / 15kv-3 * 300 Meaning: refers to the copper core XLPE insulated double steel tape armored PVC sheathed power cable, cable rated working voltage 8.7 / 15KV, cable for the three-core, single Conductor cross-sectional area of 300mm2. YJ: cross-linked polyethylene insulation V: PVC sheathed 22: steel tape armor 8.7 / 15KV: rated working voltage 8.7 / 15 kV 3 * 300 Specifications: YJV22-8.7 / 15kv-3 * : Three conductors, single cross section of 300 square feet.
Q:Why cross bonding in power cable?
If so, the answer is: By tying multiple cables together, the current carrying capacity of the total cable is increased without having the total cost increase in proportion. In other words -- using the picture as an example -- tying 4 equal sized cables together increases the current carrying capacity by a factor of 4, but the cost of this multiple-wire cable is less than the cost of a larger single cable that would carry an equal amount of current. .
Q:i only have a power cable for my ps3 how do i set it up with hdmi cable ?
