2.Operating Characteristics

Rated voltage U0/U(Um): 26/35(40.5)kV
U0 is the rated power frequency voltage between conductor and earth or metallic screen for which the cable is designed;
U is the rated power frequency voltage between conductors for which the cable is designed;
Um is the maximum value of the “highest system voltage” for which the equipment may be used.
Max. permissible continuous operating temperature of conductor: 90 °C
Max. temperature of conductor during short-circuit (5s max. duration) shall not exceed: 250 °C
The ambient temperature under installation should not be lower than: 0 °C
The bending radius of cable is recommended as following:
For single core cable: not less than 20 times of the diameter of cable
For three core cable: not less than 15 times of the diameter of cable

 

3.Application
The cable is used for fixed installations such as electric power distribution networks or industrial installations, which is laid indoors, outdoors, in tunnel or in cable trench, unable to bear external mechanical force.
Single core cable in magnetic duct is not permissible.

Q:What does the cable ZR-YJV22-4 * 16 mean?
Copper core XLPE insulated PVC sheathed flame retardant power cable, three core, nominal cross section 6 square millimeters, rated voltage 0.6 / 1kV, model specification specification: ZR-YJV0.6 / 1KV3X6mm ^ 2.
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:Power cable ZRYJV-4x70 + 1x35 What does it mean?
2 cable in a variety of environments in the laying of the layout, spacing should meet the design requirements
Q:Which has, know the power of the electrical, choose the cable formulas. And explain it
The audio line to use a shield of the special line, shielded cable and TV open to the road, the state is 1 to more than the signal line, the outer layer of metal mesh, with this line It will be disturbed.
Q:Calculate the control cable under what circumstances the cable terminal needs to be calculated
" Why should the closed wall or protective wall closed on the second side of the closed junction box? This need to understand if you do not add this closed junction box, what kind of harm Civil air defense project in the closed wall is divided into the clean area and the area of ​​the infected area, and the wire tube in the thread after the inside is a cavity, directly through the wall to communicate with the cleaning area and exposed areas, so wartime works outside the dyeing The poisonous air can penetrate into the clean area through the cavity inside the wire tube, which is harmful to the personnel inside the project And the installation of a sealed junction box, you can thread in the line after the box filled with sealing material to block the tube cavity connectivity This is why the electrical safety pipe in the air defense project must pass the closed wall or protect the closed wall when the two sides must be closed in the closed junction box reasons
Q:W22 in the cable on behalf of what
Not W, is VVVV22 means the meaning of plastic insulated plastic sheath with armored copper cable. Wire and cable: wire and cable is the transmission of electrical energy, electrical signals and electromagnetic energy conversion to the wire products. Cables are usually made up of cable cores that transmit electrical or electrical signals and protective, insulated sheaths. A cable with only one cable core and a smaller diameter is often referred to as a wire. Also some wires do not have insulated sheaths, called bare wires. The cable in the cable is made of a metal material with good electrical conductivity, usually copper (good electrical conductivity) or aluminum (lower cost).
Q:How to identify the quality of the lock of the hotel lock?
If you are using a cable that is suitable for direct burial, you do not need a casing. But in the place into the building, should be casing, in order to protect. General steel pipe can be.
Q:1omoons / days sensitive quad-core network set-top boxes can be used on old-fashioned televisions.
Pipe protection cable to wear metal hose, metal hose and galvanized pipe to use metal lock connection, the connection can not pull the light pull on the line. If there is no metal hose or no metal lock, in the pipe when the pipe toward the cable to the appropriate bending, preferably in the mouth of the cushion cable skin, and then use the electrical adhesive tape sticky, sticky. After the nozzle cut with a polisher smooth grinding, the provincial scratch cable.
Q:What is the difference between a shielded cable and a control cable?
If there is a number of casing is the number of lines marked, if the line before the iron circle is a small nose, line nose in addition to a small circle and fork, and fork almost look.
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
