Q:Will the two 16 square copper wire with what specifications of the trunking
WZC: W-halogen-free, ZC-flame retardant class C F46-poly perfluoro-propylene propylene Y - polyolefin sheath 2 - steel tape armor 2 - PVC outer jacket
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:What is the interface between the power interface and the hard disk?
10KV generally in the bottom, 380V power cable in the middle, control cable and cable at the top
Q:What are the varieties of wire and cable (detailed point)
DJ is a distributed instrument signal cable, also refers to the computer cable, V is PVC. The specific meaning can see the manufacturer's product description.
Q:Which has, know the power of the electrical, choose the cable formulas. And explain it
Basically are refining, the wax is also used, the high cost of particles
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:Will the computer master, external DVD burner how external power supply, please click details. Thank you!
Regardless of multi-wire or single-core, as long as it is in line with national wire standards, and now the market is not the current market line 60% compliance. To select the regular products, national safety certification, safety standards, a good installation process and the standard of the wire, a local demand for electricity with the appropriate diameter. To ensure that you are comfortable with electricity,
Q:What is the difference between a trough bridge and a tray tray?
Many, with the cable where the requirements should be used bridge.
Q:Copper core power cable models which several kinds
First, the total number of wire and cable products are thousands, applied in all walks of life
Q:How long is the service life of the cable?
cable bridge and other pipes and other facilities shall not share a column (bracket)
