Product standard:

GB/T12706.1-2008

Application:

This product is suitable for power transmission and distribution line of rated voltage (U0/U) 0.6/1.0KV line.

This cable is used for power supply in low-voltage installation systems for indoor and outdoor, cable ducting, underground, power and switchyards, local energy distribution, and industrial plants.

Using Characteristics:

1. Working temperature: 70~160 °C.

2. Ambient temperature:>0 °.

3. Minimum bending radius is 10 D (“D” refers to cable diameter)

4. Has good chemical stability, acid, alkali, salt, oil, solvent, flame retardant and other properties.

5. The maximum allowable operating temperature for long-term working conductors is 90 degrees.

6. Short circuit (up to 5 seconds maximum). The maximum temperature of the conductor does not exceed 250 degrees.

7. There is no horizontal drop limit for cable laying. The ambient temperature during laying should not be lower than 0 °C. Otherwise it should be warmed up.

8. excellent electrical properties, chemical resistance.

9. Good traction can be maintained when laying. Traction can be pulled from the outside. Low smoke and halogen free after combustion. Re-burn the cable.

Filler

The filler can be extruded or ground. For cables with a round core, in addition to cables with more than five cores, overlapping inner covers are only allowed when the gap between the cores is substantially filled. A suitable adhesive is allowed prior to application of the extruded inner cover. Materials used for internal coverings and fillers should be suitable for the operating temperature of the cable and compatible with the insulating material. For halogen-free cables, the inner covering and filler should also be halogen-free.

Armor

According to IEC 60502-1, aluminum/galvanized steel/steel wire is spirally applied to the inner cladding, or double aluminum/steel strip and copper/tinned copper wire can be produced as required.

Outer sheath

The outer sheath shall be extruded PVC type ST1 / ST2 according to IEC 60502-1, polyethylene type ST3 / ST7, halogen-free compound ST8, polychloroprene, chlorosulfonated polyethylene or similar polymer, SE1 type also Available on request.

Fire protection performance

The cable can be supplied with a special flame-retardant PVC outer sheath to meet the flame test requirements of IEC 60332-3-22, IEC 60332-3-23 and IEC 60332-3-24, halogen-free materials in accordance with IEC60754-1 / 2 and IEC 60684-2.

Applications
These cables are used for electricity supply in low voltage installation system, They are suitable for installation in indoors and outdoors, in cable ducts, under ground, in power and switching stations, local energy distributions, industrial plants, where there is no risk of mechanical damage. The lead sheath brings an enhanced resistance to aromatic hydrocarbons.
