VV cable is a power cable that it is used commonly, because the price is relatively low and widely used in many fields.
Use features:
Long-term Allowable Working Temperature: not exceed 70℃;
Short circuit maximum operating temperature of cable conductor does not exceed 160℃ (the longest lasting 5s);
Cable laying temperature not lower than 0℃.
Minimum bend radius of the cable laying (D for the cable outer diameter): Single core non-armored cable to 20D, multi-core non=sheathed cables 15D, single core armored-cables 15D, multi-conductor armored cable to 12D.
According to the cable VV and VV22 armor can be divided into two types.The biggest difference between the two models is that without armor VV, VV22 models with armor.

Product models | Name | Laying occasion | Cores number | Nominal cross section (mm2) |
VV | Copper conductor PVC insulated and sheathed power cable | For laying indoors, tunnels, ducts, pipes, flammable and severe corrosion and unable to bear external mechanical forces place. | 1-5 | 1.5-800 |
VV22 | Copper conductor PVC insulated steel tape armored PVC sheathed power cable | For laying indoors, in tunnel, cable trench, underground, flammable and severe corrosion and unable to bear pulling forces place. | 2-5 | 1.5-800 |
Note: the above list can produce flame retardant product (before the above products plus ZR model which represents the product of flame retardant). In limited range, the main features of the flame retardant type power cable is difficult to fire or after fire retardant, the cable is suitable to lay in hotels, railway stations, chemical, oil platforms, mines, power stations, subways, high-rise buildings and cable flame retardant requirements of the occasion. Addition to a common power cable characteristics, fire-resistant cable also running within a certain time, when in the event of a fire burning. Especially suitable for fire alarm, fire fighting facilities, fire emergency evacuation and other distribution systems. | ||||
Application:
Suitable for AC rated voltage is 0.6/1kV and below transmission and distribution lines.
Different core numbers are in different products specifications, both VV type and VV22 type are in different core number and product specification.

The finished cable conductor DC resistance (The data is consistent with the table above.)
‚The finished cable insulated normal resistance can’t lower than 36.7 in heated house.
ƒThe finished cable can withstand 50Hz AC voltage test in heated house. Single-core unarmored cable after being immersed in water for 1h should be with voltage test.

Company Information
Our factory is about 350,000 square meter with register capital about 300 million.500 stuff and 28 engineers.It has reached 10 billion annual output value.
We own standard workshops, excellent production lines and detection devices. By powerful technical force, we own a senior talent team which has been engaged in cable production & management for many years.
We have advanced process equipment/world-class production line,these include automatic PVC granulation equipment, Taiwan full-automatic cable wrapping equipment, USA importing bar code system.and Germany importing 14-head and 16-head Niehoff equipment which are the wire drawing machine ,the most it can draw at the same time is 14 and 16 or below.And the 16-head one can draw copper wire to 0.17 square millimeter just like the thickness of human hair. Full-automatic cable wrapping equipment, one-step silane crosslinked cable.And we also have the granulation 35kV triple layers co-extrusion cross-linking production lines to produce the 35kV and below multi functional electric wires and cables are well received by the market.
All the raw materials are purity which are purchased from TPCO,Armer International Group,Jiangxi Copper Corporation and other domestic globalization-based groups.Using 99.99% oxygen-free copper core , the products of the indicators are much better than the national standard. Less resistance, better conductive properties, lower heat, less carbon and more environmentally friendly
