Q:Yjv22 cable laying pipe when the casing with plastic or steel pipe
(4 × 185 + 1 × 95) is the cable specifications, indicating that the cable has 5 cores, of which 4 cores are 185 Square millimeters, one core is 95 square millimeters. General 185 line is the main core, power with, 95 for the ground core, ground use.
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:The power cable troughs are divided once and twice
Can be used for overhead, buried and pipeline laying of the cable line
Q:Why does the AC welding machine burn out the equipment?
Electric workers in the wood when the wood bar, buried in the soil that part of the first use of fire char, and then brush into the ground after the bitumen
Q:Construction of hydropower embedded pvc pipe after the solidification of the pipe after the flat tube
Cable model NHYJV3 * 25 + 2 * 16 its name is: fire-resistant cable. NH ----- on behalf of fire. YJV ----- XLPE insulated PVC sheathed power cable. 3 * 25 ----- 3 cable cross section is 25 square (for 3 phase line with). 2 * 16 ----- 2 cable cross section is 16 square (one for the neutral line, one for the ground line). Fire-resistant cables are generally used for TN-S power supply systems (five-wire).
Q:What is the installation specification for the cable tray bracket?
WDZ low smoke zero halogen flame retardant power cable. WDZN low smoke zero halogen flame retardant power transmission cable. W-halogen-free, D-low smoke, Z-flame retardant, N-refractory, YJ-XLPE insulated, V-PVC sheathed YJV-XLPE insulated PVC sheathed power cable. Model of the principle of omission: wire and cable products, copper is the main use of the conductor material, so the copper code T write, but bare wire and bare conductor products except. Bare wires and bare conductor products, power cables, electromagnetic wire products do not indicate a large class code, electrical equipment, wire and cable and communication cable category is not listed, but set out small class or series code. Item 7 is a special use of special occasions or additional special requirements of the mark, in the "-" after the alphabet letters. Sometimes in order to highlight the item, write this to the front. Such as ZR- (flame retardant), NH- (refractory), WDZ- (low smoke and halogen, enterprise standard), TH- (for hot and humid areas), FY- (anti-termite, enterprise standard).
Q:What is the wiring principle in the home improvement circuit?
This is not the end of the family with a good audio and video lines are thousands of dollars I do not know what kind of advice you want to go to the local workers Duan Gengmang Gama moths tied to the supermarket stall can find!
Q:What type of cable is the power cable?
Our unit to do the professional cable tray to the current domestic ranking before 3 I did not see we have this certification ah there is a professional health and safety management system has an environmental management system and other quality management system of other scientific and technological innovation patents have a lot of what I do not see the CCC, but you can do the next try you can log in China certification recognized information network - expert column, consult the above experts, these experts have all walks of life experience, can help to you.
Q:How high voltage armored power cable is grounded
Insulated isolation of the double shield control cable is the outermost armor layer should be grounded at both ends, the inner shield one end of the ground, is conducive to the rapid release of induced current.
Q:3 (WDZBN-YJV-4x240 + 1x120) cable how to interpret
In fact, this is a wrong model! (WDZBN-YJV-4x240 + 1x120) - 3 cables, each copper conductor Conductive cross-linked polyethylene insulated PVC sheathed halogen-free low smoke Flame-retardant fire-resistant power cable 4-core 240mm² + 1-pin ground protection line 120mm². As we all know, polyvinyl chloride is halogen-free, not "halogen-free". The correct model should be: 3 (WDZBN-YJE-4x240 + 1x120) - 3 cables, each copper conductor Conductive cross-linked polyethylene insulated polyolefin sheathed Halogen-free low smoke Flame-retardant fire-resistant power cable 4-core 240mm² +1 core grounding protection line 120mm².
