Use

Used for fixed installation on power transmission and distribution lines with AC 50Hz and rated voltage of 6kV~35kV, for transmitting and distributing electrical energy.

Cables are allowed to be laid indoors, outdoors, in the air, and buried in the soil, and local water accumulation is allowed

The laying methods can be tunnels, pipelines, cable trenches, cable trays, and ducts. Armored cables are allowed to be buried directly underground

Single core cables are not allowed to be laid inside magnetic metal pipes

Single core armored cables are made of non-magnetic metal materials

The cable laying environment should have good heat dissipation conditions

Conductor characteristics

The conductor is made of aluminum iron alloy material and adopts overall annealing process. The tensile strength of the conductor single wire is between 98~159MPa, and the fracture productivity is not less than 10%. It has good flexibility, creep resistance and corrosion resistance.

Special properties of cables

Flame retardant/halogen-free low smoke flame retardant

Oil resistant/UV resistant/heat-resistant/low-temperature resistant

Anti termite/anti rodent/waterproof

Rated operating temperature of conductor

The maximum rated working temperature of the cable conductor is 90 ℃, and during a short circuit (with a maximum duration of 5 seconds), it does not exceed 250 ℃

Allowable bending radius of cable

Single core cables should not be less than 20 times the outer diameter of the cable, and three core cables should not be less than 15 times the outer diameter of the cable

cable structure

The main structural components of the cable are: conductor, insulation layer, shielding layer, and protective layer

among which
