Medium and high voltage cables

Cross-linked polyethylene insulated power cables use chemical or physical methods to transform polyethylene molecules from linear molecular structures to three-dimensional network structures; from thermoplastic polyethylene to thermosetting cross-linked polyethylene, which greatly improves Improved its heat resistance and mechanical properties, and maintained excellent electrical properties. The conductor working temperature of the cross-linked polyethylene insulated power cable is 90°C, and it has the characteristics of simple structure, light weight and chemical resistance, easy to use, and not restricted by the installation drop. The cables are used in power frequency voltage U0/U6/6 (6/10), 8.7/10 (8.7/15), 12/20, 26/35 (26/45) kV power transmission and distribution systems.

1. 1. U0-The rated voltage between the conductor used in the cable design and the metal shield or sheath;
Rated power frequency voltage between conductors for U-cable design;
Um-The maximum value of the highest system voltage that the device can withstand;
2. 2. U0 is divided into two categories according to the duration of the system ground fault, the specific categories are as follows:
Type 1 cables are used in systems where the single-phase ground fault time is generally not more than 1 mim each time, and can also be used in systems where the longest time is not more than 8h, and the cumulative annual time is not more than 125h.
Category 2 cables-used in systems with longer ground fault times and where higher requirements for cable insulation performance are required, Category 2 should also be adopted.
Typical structure description
1. 1. Conductor
The conductor part is composed of copper or aluminum and is tightly compressed and stranded by a nano-stretching die. It has the characteristics of smooth surface, good roundness, and large compaction coefficient.
2. 2. Semi-conductive shield
The semi-conductive materials of the conductor shielding and insulation shielding are all cross-linked, super smooth, and can adapt to three-layer co-extrusion.
3. 3. Insulation
The 35kV insulation material adopts imported ultra-purified cross-linked polyethylene material, and the purification level of the feeding system in the production process is 1000, which strictly guarantees the purification degree of the raw materials.
4. 4. Metal shield
Copper tape is used to meet the requirements of mechanical properties and short-circuit capacity.
5. 5. Inner sheath and filling
The filling is made of polypropylene tear film and the stranded filling rope, which can prevent the longitudinal penetration of water and increase the service life of the cable.
The inner sheath can be made of PVC plastic according to customer requirements; if the cable has waterproof requirements, the inner lining layer is made of extruded black linear low-density polyethylene.
6. 6. Armour layer
To meet the requirements of withstanding mechanical external forces during installation and laying, galvanized steel strips are used.
7. 7. Outer sheath
According to customer requirements, PVC and PE plastics can be used, and ordinary, flame-retardant, halogen-free and low-smoke, anti-termite, anti-rodent, weather-resistant, etc. can be provided. Its thickness is determined according to the outer diameter before extrusion or the international standard provided.

1. 6-35kV cable core allows long-term maximum working temperature of 90℃.
2. The core short-circuit temperature shall not exceed 250℃, and the maximum duration shall not exceed 5 seconds.
3. Bending radius
Single core cable allowable bending radius: 20(d+D)±5%
Allowable bending radius of multi-core cable: 15(d+D)±5%
D-The actual outer diameter of the cable sample (mm),
d-The actual diameter of the conductor (mm).
4. Laying is not restricted by the horizontal drop.
5. Laying temperature
When laying below 0℃, it must be heated in advance.

Delivery length
The delivery length of the cable should not be less than 100m, and the measurement error should not be greater than ±0.5%.
24 cores and below: It is allowed to deliver short cables with a length of not less than 20 meters, and the quantity should not exceed 5% of the total length of delivery.
More than 24 cores: It is allowed to deliver short cables with a length of not less than 20 meters, and the quantity should not exceed 10% of the total length of delivery.
According to the agreement between the two parties, any length of cable is allowed to be delivered.
Packaging signs and transportation
Cables in coils or coils should be neatly wound and properly packaged.
Each circle or plate should be attached with a label indicating:
Manufacturer name or trademark
Cable model and specification mm2
Rated voltage V
Length m
Manufacturing Date: Year Month
Standard number
Gross weight kg:
Correct rotation direction of the cable reel
Transport and storage
Spools are not allowed to lay flat
During transportation, it is strictly forbidden to lower the cable reel with cables from a high place, and it is strictly forbidden to lose the cables mechanically.
When hoisting packages, it is strictly forbidden to hoist several trays at the same time. On vehicles, ships and other transportation tools, the cable reel must be placed firmly and fixed with a suitable method to prevent mutual collision or overturning.
