Q:How to connect the power cable pre-branch connector
In the pre-measured size cut out the jacket and insulation, according to the different cross-sectional size of the cable cut the size of the jacket and insulation different; with C-shaped tube corresponding to the corresponding color sequence crushing the trunk and branch lines, crimping attention to crimping The strength of the clamp, can not be too loose or too tight, too loose will cause the cable crimping off, resulting in open circuit, crimping too tight will break the conductor or cause the conductor stranded in the contact with a good conductor with polytetrafluoroethylene With the winding baking transparent, and then wrapped waterproof tape (tiger belt) can be used after the wooden hammer shrink the cable core to facilitate injection molding in the injection process should choose the appropriate mold and injection molding machine injection mold injection, the mold is too large cost Waste, the mold is too small caused by defective, bad seal at both ends of the running coke, affecting the injection effect
Q:What is the use of wire and cable per square meter of residential building?
Generally wear SC65 tube. If the distance is too long, elbow and more, then the choice will be larger.
Q:110 voice patch panel directly to the telephone line can be connected to it
sure. Take the ground pipe is to be from the floor under the brick. But the late completion of the drawing to be accurate, so that the next time to repair the line can not find the location. Want to answer to help you.
Q:Ceiling on the wire after the tube is the tube on how to fix it on the ceiling?
General telephone lines, lighting control lines or wire diameter in the 1.5 square millimeters of small lines with 4 points. More than the aforementioned line will use the 6 points.
Q:PVC pipe line 6 points and 4 points which big ah?
35 square copper wire current carrying capacity is 105A, 105A / 35 mm2 = 3A, (1 square millimeter carrying capacity is 3A) 70 square copper wire current carrying capacity is 169A, 169A / 70 square millimeters = 24A (1 square millimeter carrying capacity is 24A) 1 square hai load current from 11A gradually become 24A So it is impossible to use n by the coefficient can be drawn to the current value Wire can carry the current * the applied voltage * power factor = can drive power The diameter of the wire with different diameter is not the same No specific diameter can not know the current carrying capacity How much power, depending on the voltage level Because P = UI As the saying goes: a square 4 current, underground than this small forget How much is the square here is a square millimeter Power depends on your voltage, the general small line can be directly by 5 is to eat the current to 50-120 the basic can take more than 35 can take 25 or so just personal experience to do reference to the need for basic data: 1 line, copper and iron Aluminum silver temperature 3 core number 4 diameter Probably take a square 5A diameter n square of the wire can be over n high current, resulting in n high power so that can be calculated
Q:Why does the AC welding machine burn out the equipment?
Cable bridge spray to improve the corrosion resistance and anti-aging. Spraying the cable tray is the electrostatic powder coating equipment to spray the powder coating to the surface of the bridge, under static electricity, the powder coating will be evenly adsorbed on the surface of the cable bridge to form a powder coating, powder coating layer through the high temperature baking flow Flat and cured, into the effect of different (different types of powder coating effect) the final coating. Spraying effect in mechanical strength, adhesion, corrosion resistance, aging resistance and other aspects are better than the painting process, the bridge body metal can play a good protective effect, the cost is also under the same effect of paint. The basic principle of electrostatic spray technology is the static generator to produce negative high pressure (10KV or so), the use of corona discharge phenomenon powder coating (a variety of colors) adsorption on the metal parts, powder coating by the supply system by compressed air Nozzle, the front end of the nozzle with a high voltage generated by the high voltage static generator, due to corona discharge, in the vicinity of the dense charge generated by the powder from the nozzle when the formation of charged paint particles, it is the role of electrostatic force , Is adsorbed to the metal parts up, after heating the powder melting, and natural cooling curing, in the workpiece surface to form a hard coating. This kind of spray cable tray is made of this.
Q:Construction of hydropower embedded pvc pipe after the solidification of the pipe after the flat tube
The TV has only one set of video audio inputs that can no longer be tapped to other devices, which are limited by the hardware port, unless you change the TV.
Q:The difference between power cable and overhead cable
. the power cable occupies less. Generally buried in the soil or laying in the room, the channel, the tunnel, the line between the insulation distance is small, no tower, covers an area, basically does not occupy the ground space. The overhead cable is the opposite. . power cable reliability. Affected by climatic conditions and the surrounding environment, transmission performance is stable, high reliability. . the power cable has to ultra-high pressure, large capacity development of more favorable conditions, such as low temperature, superconducting power cables. . the power cable distribution capacitor larger. Overhead cable is the opposite . the power cable maintenance work less overhead cable is the opposite . the power cable electric shock is unlikely. The overhead cable is the opposite
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:What is the role of patch panels generally, why should the switch connected?
If you are in a small city or town, go to some of the aluminum core series of cable (if you are in a small city or town), if you are in a big city, ask high, with copper core BV, BVVB, RV, VV series line Better, according to the level of regional economic development to purchase the cable, wire type.
