Product Description

XLPE Insulated Power Cable (up to 35kV)

Sieben Group is a dedicated Chinese Electric Manufacturer including Cable & Wire, Distribution Box, Cable Accessories and so on.

XLPE Insulated Power Cable is used to transmit electricity on AC 50Hz power transmission and distribution lines with rated voltage 35kV or lower. Compared to PVC Insulated Cable, XLPE insulated electrical conductor boasts excellent electrical and mechanical properties, heat and aging resistance, environmental load resistance and chemical corrosion resistance. The simple and light-weight structure of the electrical cable allows for easy installation.

Standard Compliance for XLPE Insulated Power Cable

1. GB/T 12706.1-2008 (refer to IEC 60502-1) Rated Voltage 1kV(Um=1.2kV) and 3kV(Um=3.6kV)
2. GB/T 12706.2-2008 (refer to IEC 60502-2) Rated Voltage 6kV(Um=7.2kV) and 30kV(Um=36kV)
3. GB/T 12706.3-2008 (voltage grade exceeding IEC 60502) Rated Voltage 35kV(Um=40.5kV)

Working Conditions for XLPE Insulated Power Cable

1. Max working temperature of the insulated power conductor is 90ºC. In case of a short (lasting less than 5 secs), the max temperature of the cable conductor shall not exceed 250ºC. Environment temperature should be no lower than 0ºC when laying the cable.
2. Bending radius allowance of XLPE Insulated Power Cable

Single core cable: unarmored cable 20D; SWA cable 15D
Cores Cable: unarmored cable 15D; SWA cable 12D
Notes: D = Practical external diameter of cable.

Type, Description and Application: (Table 1-1)
Table 1-1 Type Description & Application Occasion of cable

Type		Description	Application Occassion
Cu	Al
YJV	YJLV	XLPE insulation PVC sheath power cable	To be laid indoors, in tunnel, cable furrow or pipe, the cable couldn't bear mechanical force outside
YJY	YJLY	XLPE insulation PE sheath power cable
YJV22	YJLV22	XLPE insulation, steel tape armor, PVC sheath power cable	To be laid underground, the cable could bear certain mechanical force, but it couldn't bear great pulling force.
YJV23	YJLV23	XLPE insulation, steel tape armor, PE sheath power cable
YJV62	YJLV62	XLPE insulation, have no the magnetism steel tape armor, PE sheath power cable
YJV32	YJLV32	XLPE insulation, thin steel-wire armor, PVC sheath power cable	Be applicable to the well, water inside and fall in the bad soil, the cable can bear the equal dint outside the machine with pull the dint
YJV72	YJLV72	XLPE insulation, have no magnetism thick steel-wire armor, PVC sheath power cable
YJV42	YJLV42	XLPE insulation, thick steel-wire armor, PVC sheath power cable	Be applicable to the well, underwater with the bottom of sea, the cable can bear the bigger pressure with lead to pull the dint.
Hint Specially	The single-core magnetism material packs the cable is not suitable to use for AC power supply back track, the necessity hour eligibility uses the single-core 62 or 72 type pack the cable. Disallow the cent to cross the magnetism piping mutually when single-core cable establish, in order to prevent results in the descent that cable transport electric current ability.
