0.6/kV XLPE insulated power cable specifications and carrying capacity 
 (Including the common type, flame retardant, fire-resistant, halogen-free flame retardant type) 
 1. Features and uses 
 XLPE insulated power cable with high mechanical strength, good resistance to environmental stress, good electrical properties and chemical resistance characteristics, light weight, simple structure, easy to use. This product is suitable for AC rated voltage Uo / U is 0.6/1kV and below the transmission and distribution wires on the road. 
 The main features of flame-retardant power cable is the cable delay is not easy to fire or fire burning within a certain range is only limited for the higher intensity of laying the cable stations, subways, tunnels, high-rise buildings, large industrial and mining enterprises, oil, coal, etc. place. 
 The main features of fire-resistant power cable is the cable in addition to normal working conditions in the transmission of electricity, cable can maintain the fire burning for some time when the normal operation for nuclear power plants, subways, tunnels, high buildings and fire safety and fire rescue the place. 
 LSZH cable is characterized not only with flame retardant cable, and has low smoke and harmless (less toxic and corrosive), applies to cable fire, smoke density, toxicity index places with special requirements, such as subways, tunnels, nuclear power plant. 

 2. Product Standards 
 The product according to GB / T 12706-2002, or IEC 60502 standards for production, but also according to user requirements and other standards. 
 Flame retardant cable in addition to the above criteria, the fire-retardant properties according to GB/T18380.3-2001 standard is divided into A, B, C are three different types of flame, A flame-retardant properties of the optimal level category, the user can According to the need to use. 
 The fire resistance of fire-resistant cable should meet the GB/119216.21-2003. 
 Halogen-free flame retardant cable according to corporate standards for production, fire-retardant properties according to GB/T18380.3-2001 standards are divided into A, B, C of different types of flame, smoke density requirements by GB/T17651-1998 test, PH value and conductivity should be consistent with GB/T17650.2-1998 requirements.

 Fourth, the product features 
 (1) Rated voltage Uo / U is 0.6/1kV. 
 (2) the highest rated cable conductor temperature of 90 ℃. 
 (3) short (the longest duration of no more than 5S) maximum cable conductor temperature does not exceed 250 ℃. 
 (4) of cable laying temperature should not be less than 0 ℃, the minimum bending radius is as follows: 
 Single-core non-sheathed cable: 20D 
 There are single-core armored cable: 15D 
 Three-core non-sheathed cable: 15D 
 There are three core armored cable: 12D 
 (Note: D is the cable diameter) 
 Fifth, the main technical parameters 
 Cable ampacity calculation conditions 
 Ambient temperature: in the air laying 40 ℃; laid underground 25 ℃. 
 Cable conductor temperature 90 ℃ 
 Cable is laid underground, the soil resistance coefficient g = 1.0 ℃ · m / W, but not yet considered a long cable run as a result of soil moisture migration phenomenon of increased thermal resistance coefficient. 
 Cable is laid underground, the cable axis and the ground distance of 700mm. 
 More flat-shaped cable laying, cable axis distance S = 2D
