Product Description:

Rated  voltage 1kV1.2kVand3kV(3.6kV)

PVC insulated Flame retardant and Fire  resistant cables

XLPE insulated Flame retardant and Fire  resistant cables

Brief  introduction

PVC insulated Flame retardant  and Fire resistant Power cables are fixed laid in the circuit with frequency  50Hz and voltage upto 3.6/6kV.

XLPE  insulated Flame retardant and Fire resistant Power cables are fixed laid in the  circuit with frequency 50Hz and voltage upto  3.6/6kV.

We can  produce Flame retardant and Fire resistant with PVC or XLPE insulated power  cables according to standard GB/T19666,Grade A, B,C or  D.

Rated  Voltage 0..6/6kV3.6/6kV

Conductor of cables can be  Copper and Aluminum.The cables can be single core,two cores,three cores,four  cores(including three main cores and neutral).five cores (including three main  cores and neutral and one earthing core,Four main cores and one  neutral).The cables can be with armour and  without armour.

We can produce cables with PVC  outer sheath,Flame retardant PVC outer sheath or with fire resistant  insulation.The cables are produced according to GB/T12706(eqvIEC60502) and  GB/T18380-2001(eqv IEC60332),or GB/T19216(IEC60311) and or the BS,DIN, or other  international standards. And we also design and produce cables according to the  requirement of our clients

Application

1、           Long term working  temperature for the cable with PVC insulated is 70

Long term working temperature for the cable with XLPE  insulated is 90

2、           Short circuit  temperature

For PVC insulated cable ,the highest  conductor temperature is not more than160℃.(lasting time not  over 5 seconds)。

 For XLPE insulated cable ,the highest conductor  temperature is not more than250℃.(lasting time not  over 5 seconds).

3、           Laying temperature not less than  0℃ and  the drop height is out of consideration。

4、           The cable with chemical stability,anti  acid,anti alkali, anti oil,anti organic solvent,not easy to be  burning

5、           Easy for installation,easy bending and  light

6、           Bending ratio

Q:What does the cable (YJV-5 * 6) mean?
Full name: cable ZR-YJV22-4 * 16MM2ZR: flame retardant ----- YJV22: copper conductor cross-linked polyethylene insulated PVC sheathed double steel belt wrapped armored power cable --- 4 * 16MM2: 4 core, each core 16 square millimeters.
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:Power Cable Check Well b-type covers show what?
B-grade steel fiber concrete check covers are used for motor vehicle driving, parked urban roads, highways and parking lots C-grade steel fiber concrete check covers for slow lanes, residential quarters and sidewalks D-grade steel fiber concrete inspection covers for green belts and motor vehicles can not travel, parked lanes and venues
Q:What is the installation specification for the cable tray bracket?
Be careful is right, but it is not necessary to be timid. Need to do so: . ask the district property, if the best road distribution map, read the drawings, you know where the cable, where not. . ask your home decoration of the electrician, he knows the most where your house where there is a wire decoration. . the general wall cabinet installed relatively high, as long as the bottom of the socket to avoid, generally all right.
Q:Fourth, what causes the power cable fire accident
After the cable is burned out, the repair time is long and the loss is serious
Q:Choose the configuration of good or bad computer graphics card memory processor, etc., how to choose a different manufacturers
Calculation method: the amount of engineering calculation formula: L = (pipe length calculation + wire reserved length) × with the number of cross-section wire. Note: plastic pipe should not be flattened, cracks, no debris in the tube, cut the mouth should be flat, the nozzle should be shaved plastic wire pipe connection using glue bonding, plastic pipe bonding must be tightly tight, and in the pipeline plug on the plastic pipe plug, to prevent the paddle, plug tube concrete floor, wall and brick structure of the various switches, socket bottom box , The lamp junction box and the pipe connection must be connected with the wiring, is strictly prohibited plastic pipe directly into the junction box dark in the concrete junction box requirements with wet cement paper or plastic foam filled with internal, not allowed to use The cement paper packs its outside. Embedded in the floor, the shear wall of the plastic pipe, the junction box should be fixed firmly to prevent the shift
Q:What is the difference between a trough bridge and a tray tray?
The line is to be reserved, the installation will have a certain degree of tightness
Q:What is the warranty period for wire and cable?
General cable maintenance period is about 15 years, but to ensure that the normal use of the environment, such as the amount of temperature is below 70 degrees, but you are more than 70 working environment to use, of course, may not be used for a year. Therefore, the most important thing is to follow the instructions to use. Wire and cable recommended Ogilvy's.
Q:How to determine whether the square of the cable is standard
Depends on your number is not arranged in order, the general building room when the patch panel and the user board number is one to one correspondence
Q:Copper core power cable laying cable sets what fixed
SDH is a synchronous time division multiplexing device, the electrical interface of the 2M signal into the optical interface of the high-speed signal (the use of digital fiber optic patch panel SDHsynchronousdigitalhierarchy) 155M, 622M, 2.G, 10G, etc.). 2 trillion of the signal can be in the DDF above jumper, easy to connect. The optical path signal is spanned on the ODF and is interconnected with the optical interface of the cable or other device. Usually with the network, telephone, etc. are specific business, their communication distance is limited, are generally carried through the transmission network to expand the communication capacity, extending the communication distance. SDH is the main equipment of the current transmission network. DDF and ODF are mainly used in the machine room. The physical interface between devices is BTS-DDF-SDH-DDF-BSC-ODF-MSC or BTS-DDF-SDH-ODF-BSC -ODF-MSC Of course, bsc and msc may also have a section of ODF-SDH-ODF, see the specific circumstances
