1. The optimization design of double-layer coextruded composite insulation structure is adopted to achieve the balance of flame retardant, insulation and physical properties, which not only ensures high insulation performance, high mechanical performance, but also ensures high flame retardant performance of insulation.

2. Irradiated cross-linked process is adopted to ensure the mechanical and physical properties, electrical properties and low-smoke, halogen-free flame retardant properties of cables.

3. Under normal service conditions, the service life can reach 70 years.

4. Working temperature: The long-term allowable service temperature of cable conductor is 90°C, 105°C and 125°C; and the high working temperature is 250°C for short circuit (long duration: 5 s).

 

5. Laying temperature: Cable laying is not recommended when the ambient temperature is lower than 0°C, otherwise heating measures shall be taken.

6. Allowable bending radius of cable:

Single core cable:20D,mm     

Multi-core cable:15D,mm

D-----Actual outer diameter of cable,mm

Lifting and storage of cables

During transportation, cables and cable reels shall not be damaged. It is strictly forbidden to push the cable reels directly from the vehicle. Cable reels shall not be transported horizontally, but stored horizontally.

It is prohibited to drop the cable reel or coil containing the cable from a height. During transportation, the cable reel must be stabilized and fixed by appropriate means to prevent collision or overturning.

Before transporting or rolling the cable reel, the cable reel must be firm and the cable must be tightly wound. Rolling must follow the arrow on the cable reel or the winding direction of the cable.

Cables shall be stored centrally and classified, and shall be marked with model, voltage, specification and length. No water accumulation shall be allowed in the cable storage place.

During the storage of cables, the cable reel and packaging shall be completed, the signs shall be complete, and the ends shall be tightly sealed. Any defects shall be handled in time.

Installation and laying of cables

During cable setting-out, the tension shall be uniform, to avoid accidents caused by cracking and twisting of insulated wire core due to distortion of cable.

When cable heads are made, special tools shall be used in strict accordance with the national electric power construction specifications.

Once mechanical damage is found during the installation of cable, if conditions permit, please check the cable accordingly to confirm whether the insulation of the cable is damaged.

Before cable laying, check the cable according to the following requirements:

Cable model, specification and voltage shall conform to the design.

The appearance of the cable shall be undamaged and well insulated, and the cable shall pass the test.

According to the design and actual path, the length of each cable shall be calculated, each cable reel shall be arranged reasonably, and cable joints shall be reduced.

Reliable measures shall be taken to install and lay cables in live areas.

If you find any problems in the process of installation or use, please contact our company in time, and our company will try its best to solve your problems.
