Q:What is the heat of the cross-linked cable?
General model: SYV75-X (X on behalf of its insulation diameter 3mm / 5mm, the greater the larger the diameter of the larger) SYV S --- coaxial RF cable, Y --- polyethylene, V --- poly Ethylene
Q:Emergency cable T-box and cable distribution box of the information?
Cable distribution box according to its electrical composition is divided into two categories: one is not any switch equipment, the box only the cable end of the processing and connection of the attachment, the structure is relatively simple, smaller, more functional , Can be called ordinary distribution box; the other is not only the general distribution of the box annex, but also contains one or more switchgear, its structure is more complex, larger, more connected devices, manufacturing technology Large, high cost, can be called advanced distribution box
Q:Ceiling on the wire after the tube is the tube on how to fix it on the ceiling?
That is the two 10KV line is not specifically for you, and perhaps for others.
Q:How long is the service life of the cable?
For corrosive environments, cable trays with suitable corrosion resistant coatings should be used
Q:The TV shows no signal. The What is the reason for this?
The domestic general by the following parts in order, some parts can be omitted: 1: category, use the first letter with the Chinese alphabet, such as K on behalf of the control cable, C on behalf of the marine cable Q car ignition line D power cable Y Mobile rubber sheathed cable H welding machine cable 2: conductor with the first letter of the Chinese alphabet said: such as T for the copper, L for the aluminum LG for the ACSR 3: Insulation material with the letter code, such as V for the PVCY Polyethylene 4: Sheath with the letter of the letter code with 35: feature code used in the first letter of Chinese spells, such as the circle with R, soft R, flat B, flat with B6: outer sheath with the number that: 22 the first representative of the steel armor, the second representative of the PVC jacket 7: derived code with a number or symbol, such as BV-withered Sichuan Fen boil let go wind sand dust 90 said temperature 90 degrees BV line can be omitted Generally have: D power cable T copper R round like VV. you control the order of the above carefully understand, which omitted the 1.2.5 three, you should see clearly.
Q:Fourth, what causes the power cable fire accident
Once the cable in the event of fire, the fire ferocious, rapid spread, in the burning will occur when a large number of harmful gases, resulting in fighting difficulties
Q:TV tiger when the set-top box when tv / ay look for a look on the platform
Cable 2 * NH-KW2 * 1.. the first two said two cables, KW is KVV said PVC insulated jacket control cable,
Q:Power cable yjv22-10kv-3 * 50 what it means
This model is called copper core XLPE insulated PVC sheathed steel tape armored 3 core, each core conductor size 50mm. the cable voltage is 10KV cable. YJ: cross-linked polyethylene, cable insulation material for the chemical cross-linked polyethylene V: PVC, cable inner jacket material for the PVC jacket material first 2: plating Zinc steel strip, cable armor layer material for the galvanized steel strip Second 2: PVC, cable outer jacket material for the PVC sheathed material 10KV: that the use of the voltage of the cable waiting for you 10 kV 3 * 50 : That the cable is 3 core, each core conductor section 50mm2
Q:What is the length of the wire that affects voltage and electricity
Can go if you do not trust to wear a pvc into the bridge on it
Q:What is the difference between public relations firms and media companies?
Is the separator divides the bridge into 2 and a half, usually with two different roles of the cable at the same time laying in a cable bridge, such as the power cable with the signal cable with the bridge laying, in order to avoid electromagnetic interference, with separator separation.
