22 stands for a steel belt armored PVC sheathed power cable, which can withstand the mechanical external forces, but can not withstand the large tensile force of the insulated steel belt armored PVC sheathed power cable.
The armored cable mechanical protective layer can be added to any structure cable to increase the mechanical strength of the cable and improve the anti-corrosion ability. It is a wire & cable designed for areas that are susceptible to mechanical damage and extremely erosive. The power cable, in general, is fixed in one place and does not move basically, and the power line transmits power.
In addition to the above, the purpose of the cable plus the armor layer can also enhance the mechanical protection such as tensile strength and compressive strength to prolong the service life.
And the armor has certain anti-external force performance, it can also be used to prevent rats from biting, so as not to cause power transmission problems through armoring.
The bending radius of the armor is large, and the armor layer can be grounded to protect the cable.
I. Product Structure
YJV22 2x70mm² stranded XLPE insulated armored layer PVC sheathed power cable mainly consists of four parts: conductor, insulation layer, metal armor protection layer and outer sheath.
The conductor conforms to GB/T 3956 Class 1 and Class 2 conductor structure, and it is covered with XLPE insulation layer.
And a layer of galvanized steel strip is wrapped to protect the cable from pressure and shock.
The entire cable is outsourced as a PVC sheathing layer, and the PVC full name is polyvinyl chloride.
II. Product Characteristics
The maximum rated working temperature of the conductor is 90 °C
Conductor short circuit temperature:
The maximum temperature must not exceed 250 ° C, the maximum time is not more than 5 seconds.
Installation & laying temperature:
Cable installation & laying temperature is not lower than 0 °C
Laying in the air:
Ambient temperature 40 ° C
Laying in the soil:
Ambient temperature 25 ° C
Power frequency rated U0/U:
The bending radius of the cable:
1. single-core cable:
unarmed cable is not less than 20 times the outer diameter of the cable,
and the armored cable is not less than 15 times the outer diameter of the cable;
2. multi-core cable:
stranded unarmored cable is not less than 15 times the outer diameter of the cable,
and the armored cable is not less than 12 times the outer diameter of the cable.
III. Cable Laying Conditions&Precautions
1. The cable laying temperature should not be lower than 0 °C, and the cable should be preheated when the ambient temperature is
lower than 0 °C.
2. After the cable is laid, it should be subjected to DC voltage test for 15 minutes and the test voltage is 2.4KV.
3. Laying in the air, single core cable parallel laying center distance: 185mm2 and below is twice the cable diameter, 240mm2 and above
is 90mm, the ambient temperature is 40 ° C, the maximum allowable temperature of the conductive core is 70 ° C.
4. When laying directly buried, when the single-core cable is not in contact with laying, the center distance is twice the diameter of the
cable, the ambient temperature is 25 °C, the maximum allowable temperature of the conductive core is 70 ° C. The soil thermal
resistance coefficient is 1.0 k.m / w, and the direct burial depth is 0.7 m.
5. Cable laying should use special tools, such as pay-off racks, guide rollers, etc., to prevent mechanical damage during the laying
process, away from heat sources.
6. single cable laying in pipe:
The inner diameter of the pipe is not less than 1.5 times of the outer diameter of the cable.
multiple cables laying in pipe:
The cables are not allowed to be squeezed. And the total area of the cables does not exceed 40% of the total area of the pipe.
