TTU Cables are manufactured under the following standards:

ASTM B3,. Soft copper wire.

ASTM B8, Concentric Lay Stranded copper conductors

ASTM B787, 19 Wire Combination Unilay Stranded Copper conductors for subsequent insulation.

NET-3203. Reference Standard for Electrical Wires, Cables and Flexible Cords.

ICEA S-95-658, Power Cables rated 2000 volts or less for the Distribution of Electrical Energy.

Note: We can also produce the TTU cables as your request.

b,SWG Power Cable Construction :

Conductor: Solid or stranded copper 
Insulation: Cross-linked polyethylene (XLPE) or Polyvinyl chloride (PVC) 
Filler: Polypropylene filament with lapped binding tape 
Binder: Binding tape 
Inner sheath: Polyvinyl chloride (PVC)

c,  SWG Power Cable  Nominal Section:
Area(mm2) :1.5 2.5 4 6 10 16 25 35 50 70 95 120 150 185 240 300 400 500 630 800

d. SWG Power Cable Operating Features :
 1)The maximum conductor operating temperature: 90°C
During short circuit (lasting less than 5 seconds) the maximum temperature of the cable conductor shall not be above 250°C
Environment temperature should be no lower than 0°C for laying the cable.
2)Bending Radius of the Cable:
Single Core Cable: Non Armored Cable 20D, Armored Cable 15D
Cores Cable: Non Armored Cable 15D, Armored Cable 12D.
 Remarks: D means practical external diameter of the cable

e, SWG Power Cable Features  :

 XLPE  insulated power cable do not has excellent electric, mechanical properties,but also has powerful resistance against chemical corrosion,heat resistance and enviromental stress resistance. Its structure is simple. The long period operating temperature is +90 °C. It is conveninet to use and can be laid with no restriction of different level.

XLPE insulated steel wire armoured power cable: XLPE/PVC insulated power cable has a number of advantages over paper insulated and PVC insulated cable. XLPE cable has high electric strength, mechanical strength, high-ageing resisting, environmetal stress resisting antichemical corrossion, and it is simple construction, using convenient and higher operating of long term temperature. It can be laid with no drop restriction. 
Various of flame-retardant and non-flame retardant XLPE cable can be manufactured with three technology(peroxide, silane and irradiation crosslinking). The flame-retardant cable covers all kinds of low-smoke low-halogen low-smoke halogen free, and non-smoke nonhalogented and three classes of

A, B, C.

 2 Standard:

IEC60502,and BS6346, VDE, AS/NZS, etc or as customer's request.

 3 The Rated Voltage(kv):

1st class 0.6/1 1.8/3 3.6/6 6/10 8.7/15 12/20 18/30 21/35 
2nd class 1/1 3/3 6/6 8.7/10 12/15 18/20 - 26/35

 4 Application:

1)These cables are most suitable for direct burial or for installation on trays or ducts,  Where there is
a risk of mechanical damage, armoured cables should be used.

2) For laying in ground along route with large difference of level able to bear external mechanical forces.
