How to Use Cable Instructions?

If the cable is not used properly, it can easily lead to artillery and affect the use of cables. This article aims to introduce the use of cables Amazon Discount Code NHS.

Tools/ingredients

• cable

Method/Step

The choice of cable models and specifications should be based on the national current cable design specifications and regulations, according to the actual project setting environmental conditions, system voltage levels, load properties and load conditions.

And fully consider the degree of engineering development to correctly select the models and models of the cables and Specification.

After the product delivery acceptance product arrives at the destination, the user shall immediately perform acceptance and go through the procedures such as signatures.

The acceptance items should include: 1. Qualification certificate (one plate, one copy per plate) 2. Quality guarantee. 3. Whether the outer packaging of the cable is intact and whether it is damaged.

4. Whether the cable end is sealed, whether or not or not, or bad sealing. 5. Whether the electricity fee disk is obviously deformed and distorted.

6. Check whether the appearance of the cable is intact, whether there are abrasions, scratches, etc. 7. Whether the cable model, specifications, and length are consistent with the goods list.

Uses

the attention of the loading and unloading, transportation, storage, storage, and placement of the cable: 1. The cable disk equipped with a cable should be placed vertically, and it is strictly forbidden to place or stack.

2. The loading cable shall be lifted, and it is strictly forbidden to hang it at the same time. Pay attention to the stress position of the lifting tool. You cannot directly resign from the edge of the cable plate, the side, and the position of the plate. Strong, smooth landing.

3. The lifting tools, steel wire ropes, hooks, etc. used during loading and unloading should be greater than the total weight of the cable and packaging.

4. When transporting cables on transportation such as vehicles, the cable disk must be stable and fixed in a suitable method to prevent each other or turn over.

5. It is strictly forbidden to push a cable disk loaded from a high place. 6. Stove the cable disk placed in a stable place to ensure that the cable disc is stable, and the above rolling collision damaged cables and other accidents occur.

7. The cable is short -distance, allowing the cable to scroll, but the rolling must be consistent with the direction of the arrow indicator, otherwise it is easy to damage the cable. In addition, measures should be taken to prevent the roll on the ground on the ground rolling path.

8. Storage of cables should avoid the corrosive smell, high temperature, flammable and explosive and other places; the cables should be checked when storing the end seal, and the remaining cables on the segmenting cable disk should be taken in time.

Sealing measures to prevent cables from getting water in the end of the cable; cables should not be stored for a long time. 

Fourth, the laying and installation of the cable

The laying and installation of the cable shall strictly abide by the GB50168-92 "Specifications for the Construction and Acceptance of Electrical Device Installation Factory Cable Line", and shall be held by those who have obtained qualification certificates and practical work experience.C

Cable layout should take special equipment (such as setting racks and guide wheels) that meet the requirements. The synchronous layout method can be used to launch, mechanical transmission, and manually laying guidance.

The maximum side pressure, maximum traction, and minimum allowable bending radius must not exceed the specified value of the product when lading and lading the cable.

Side pressure: Generally not greater than 300kg.

Maximum deletion: According to relevant regulations, the maximum traction of copper core cables can be calculated by 7kg/㎜², and the allowable maximum traction tension of aluminum core cables can be measured by 4kg/㎜².

The minimum bending radius of the cable: Control cable: 6 times the armor -free and shielded soft wires greater than the outer diameter of the cable.

Power cable: single -core cable should be greater than 20 times the diameter of the cable, and the multi -core cable should be greater than 15 times the diameter of the cable.

The laying temperature of the cable should not be less than 0 ° C. If the environmental temperature of the laying site is lower than 0 ° C, the cable should be preheated. The heated cable should be laid as soon as possible. When the cable is cooled to less than 0 ° C, it shall not be added. 144HZ Laptop

When laid, measures should be taken to prevent the cables from abrasion outside, groove wall, pipe mouth, and machine. Once discovered, it must be stopped immediately. After the reason is found, it can be cleaned before it can be cleaned.

Cable

During the laying, distortions are not allowed to avoid damage to the cable. If distortions should be lifted along the direction of the distortion, you cannot knock on the cable with any tools or objects to prevent damage to the cable.

When laying, you should rotate along the circle. You cannot forcibly drag and drop to prevent the cable from distorting Amazon Discount Code NHS.

When the cable is laid upright, the buried depth must not be less than 700㎜ (the upper end of the cable is from the ground).

Good hand, it should be covered with 100 上 thick or yellow sand, and then covered with concrete or bricks. The coverage width of the coverage should exceed 50㎜ on both sides of the cable. Essence

The cable should be buried under the frozen soil layer. When buried deeply, measures should be taken to prevent cables from being damaged. Amazon Discount Code NHS 

The net distance between direct or cross -buried cables and various facilities in parallel or cross should meet relevant regulations.
