Copper Clad Aluminum Wire

CCA has its own features of density equality of copper layer, high compactness and fine en-longing capacity,which  carries many characteristics of good conductivity, high strength and strong brazing ability of copper and low density and easily to process of aluminum.  This bimetal compound lead can be used in the coaxial cable conductor with high signal transmitted features, and become the widely-used lead in CATV and other high frequency appliances. CCA is also the best choice materials for the coaxial cable conductor and cable wire of many electric equipment.

CCA Features:
1. DR Resistivity: CCA resistivity is 1.5 times that that of pure copper wire. CCA weight is about 1.2 times than pure copper wire on the same resistivity. According to the skin effect, its resistivity is the same with pure copper wire while above the 5MHZ. So CCA electric capacity is as well as pure copper wire while is used in digital cable and signal cable with high frequency.
2. Compared with pure copper wire, CCA has no value for larceners, because it become impossible to depart the pure copper cladding layer from aluminum heart yarn, so it has special function of anti-burglary.
3. With light weight, CAA is easy to transmit and fixed, on the other hand it can reduce labor cost.
4. CCA has better plasticity than copper wire, and it will never produce insulated oxide like aluminum, so it is easy to tackle with better conductivity.

5.Our products takes the international leading craftwork of cladding welding & drawing method, so even in the strict wringing test, it will never take off, craze or flake, having no harm to human health and environment.

Q:The power cable troughs are divided once and twice
Can be used for overhead, buried and pipeline laying of the cable line
Q:Power cable inspection, how many meters should be sampled?
installation quota: cable ZR-YJV-4 * 70 + 1 * 35 is a five-core cable, you can refer to sets of "copper power cable laying cable (section mm2 below) 120? Cable "quota, and the fixed sub-sub-multiplied by the coefficient 1
Q:"Cable laying" cable cross-sectional area refers to the cable cross-sectional area, or refers to the copper core cross-sectional area
What kind of clothes do you want to do? General to high-speed sewing machine, the most important three-line lock machine, hot Taiwan, such as a suit to buy a pressure machine, workstations
Q:What is the interface between the power interface and the hard disk?
YCV-copper core XLPE insulated PVC sheathed power cable, VV-copper core PVC insulated PVC sheathed power cable. YJV-voltage level (kV) 6 ~ . the maximum allowable working temperature 90 ℃ VV-voltage level (kV) 1 ~ . allowing the maximum operating temperature of 65 ~ 70 ℃
Q:Brief description of the difference between cable and cable.
Optical fiber (optical fiber) is designed to meet the optical, mechanical or environmental performance specifications, it is used in the jacketed jacket in one or more optical fiber as a transmission medium and can be used alone or in groups of communication cable Component. Fiber optic cable is mainly composed of optical fiber (such as the hair of the glass) and plastic protective casing and plastic skin, the cable without gold, silver, copper and aluminum and other metals, generally no recovery value. Fiber optic cable is a certain number of optical fiber in accordance with a certain way to form a cable core, outsourcing jacket, and some also cover the outer cover, used to achieve optical signal transmission of a communication line. That is, a fiber formed by a certain process by an optical fiber (optical transmission carrier). The basic structure of the cable is generally composed of cable core, reinforced steel wire, filler and jacket and other parts, and also need to have waterproof layer, buffer layer, insulated metal wire and other components. A cable is usually a rope of similar rope made of several or several sets of wires (at least two in each group), each of which is insulated from each other and often twisted around a center with a height Insulated cover. Cable with internal power, external insulation characteristics. Category cables are power cables, control cables, compensating cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum cables and so on. They are composed of single or multi-strand wire and insulation layer, used to connect the circuit, electrical appliances and so on.
Q:Choose the configuration of good or bad computer graphics card memory processor, etc., how to choose a different manufacturers
Calculation method: the amount of engineering calculation formula: L = (pipe length calculation + wire reserved length) × with the number of cross-section wire. Note: plastic pipe should not be flattened, cracks, no debris in the tube, cut the mouth should be flat, the nozzle should be shaved plastic wire pipe connection using glue bonding, plastic pipe bonding must be tightly tight, and in the pipeline plug on the plastic pipe plug, to prevent the paddle, plug tube concrete floor, wall and brick structure of the various switches, socket bottom box , The lamp junction box and the pipe connection must be connected with the wiring, is strictly prohibited plastic pipe directly into the junction box dark in the concrete junction box requirements with wet cement paper or plastic foam filled with internal, not allowed to use The cement paper packs its outside. Embedded in the floor, the shear wall of the plastic pipe, the junction box should be fixed firmly to prevent the shift
Q:Power cable casing buried what are the requirements
2 direct laying cable way, should meet the following requirements: 1 cable should be laid in the trenches, and should be along the length of the cable on the next, next to the side of the shop with a thickness of not less than 100mm soft soil or sand 2 along the length of the cable should cover the width of not less than 50mm on both sides of the cable protection board, protective board should adopt concrete 3 urban cable buried in the laying, it is appropriate in the protection board laying eye-catching signs 4 in the suburbs or open areas, along the cable path of the line spacing of 100m, corner or joint parts, should be erected obvious signs or signs 5 when the use of cable through the corrugated pipe laying in the trenches, should be along the full length of the bellows casting thickness of not less than 100mm of concrete, the width should not be less than 50mm outside the tube, the cable can not armor 3 buried in the non-frozen soil area, the cable embedding depth should meet the following requirements: 1 cable to the basement of the basement structure, not less than 03m 2 cable skin to the ground depth, not less than 07m; when located in the carriageway or farmland, should be properly deepened, and should not be less than 10m 4 buried in the permafrost area, should be buried below the permafrost layer, when not buried can be buried in the soil drainage of dry frozen soil or backfill, but also take other measures to prevent damage to the cable The 5 Directly laying the cable, is strictly prohibited in the underground pipe is just above or below The minimum distance between cable and cable, pipe, road, structure, etc shall be in accordance with Table 535 Table 535 Permissible minimum distance between cable and cable, pipe, road, structure, etc (m)
Q:TV tiger when the set-top box when tv / ay look for a look on the platform
. the first two said two cables, KW is KVV that PVC insulated jacket control cable. . the control cable for industrial and mining enterprises, energy and transportation sector, for the exchange rated voltage 450/750 volts below the control, protection lines and other occasions, the use of PVC insulated, PVC sheathed control cable. . the performance difference: the power cable in the main line of power systems used to transmit and distribute high-power power, control cable from the power system distribution point of electricity directly to a variety of electrical equipment, power equipment, power lines. The rated voltage of the power cable is generally 0.6 / 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 is the warranty period for wire and cable?
General cable shelf life is 10 years, look at the jacket and the insulation with or without cracks, shake the insulation resistance of the general do not breakdown can be used, but the best people to do some pressure test. The withstand voltage test must have been used.
Q:What is the difference between public relations firms and media companies?
What is the lighting type busway ah, long experience. Lighting distribution box dedicated busbar?
