Q:Cable yjv-0.6 / 1kv-4 * 120 + 1 * 70 What does it mean?
There is no difference between BTTZ25 square can only do single core. BTTZ is a kind of outer layer with seamless copper tube jacket, the middle filled with magnesia crystal powder as insulation material, the conductor is a single strand of copper rods composed of new cables, in recent years are also more used in high-rise buildings, airports, Underground railways and other places, to protect the fire in the case of fire pumps, fire elevators, local lighting, emergency evacuation instructions, security monitoring, anti-smoke system and self-powered power and other important equipment uninterrupted operation. The main features of the editor it has a high temperature, fire, explosion, no combustion (250 ℃ can be a long time running, 1000 ℃ limit state can also be 30min short time operation) and the current flow, small diameter, high mechanical strength , Long service life, generally do not need the characteristics of independent grounding wire. Application range Editor Widely used in nuclear power plants, metallurgy, chemical industry, mine, kiln and other dangerous, bad, high temperature environment. In recent years, more applications in high-rise buildings, airports, docks, subway and other places, to protect the fire in the case of fire pumps, fire elevators, local lighting, emergency evacuation instructions, security surveillance, anti-smoke system and self Power and other fire fighting and important equipment without interruption.
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:How high voltage armored power cable is grounded
When the armor leads directly to ground to buy the cable terminal, the manual has a specific production process
Q:Hello, ask about how to charge the electric car at home, use a few square millimeters of wire? How high is the demand for family lines, thank you!
PLC and computer communication cable, different manufacturers of PLC connection is not the same
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:Wire yellow and green, respectively, that line of fire or zero line
4 core 185 square millimeters plus 1 core 95 square millimeters of cable three
Q:3 (WDZBN-YJV-4x240 + 1x120) cable how to interpret
3 (WDZBN-YJV-4x240 + 1x120) cable is a low smoke halogen-free flame retardant (B grade) XLPE insulated - PE sheathed copper core power cable. The model of the cable is usually composed of eight parts: First, the use of code - not marked as the power cable, K for the control cable, P for the signal cable; so the power cable. Second, the insulation code -Z oil-impregnated paper, X rubber, V polyvinyl chloride, YJ cross-linked polyethylene; so for the cross-linked polyethylene insulation. Third, the conductor material code - not marked as copper, L is aluminum; therefore copper. Four, inner layer code-Q lead package, L aluminum bag, H rubber sleeve, V PVC jacket; so for the PVC jacket. . derived code-D no drip, P dry insulation. Sixth, the outer layer code. . special product code-TH wet tropical, TA dry tropical, ZR- (flame retardant), NH- (fire), WDZ- (low smoke zero halogen, enterprise standards); so low smoke halogen-free flame retardant The . rated voltage - unit KV; general cable are marked, the problem is estimated to write missing 0.6 / . the use of: rated phase voltage of 0.6KV, line voltage of 1KV. In the cable, 4 * 240 + 1 * 120 that there are 4 core 240 square copper wire, a 1-core 120 square copper wire.
Q:What is the power cable accessories used to do?
When using power, standby power, basically no radiation, can be considered negligible
Q:The power cable troughs are divided once and twice
Can be used for overhead, buried and pipeline laying of the cable line
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.
