Product Introduction:

Factory according to user requirements to cable main and branch cable types, specifications, cross section, length and branch position indicators, in a factory in a series of special production equipment, in the assembly line will be the finished with cable branch.

Pre branching cable is a cable which is designed by the customer to design the branch wire in the production of main cable, which is a new technology in recent years. Branch line is composed of the factory pre fabricated in the main cable, the length of the branch line section size and branch line is according to the design requirements of the decision, greatly shorten the construction period, greatly reduce the cost of materials and construction, to ensure the safety and reliability of the distribution.

Technical specifications and requirements

1) cable inspection technical requirements:

A. main and branch cables shall conform to the GB5023.11997; GB5023.21997; GB5023.31997; GB5023.41997; GB5023.71997 the rated voltage up to and including 450 / 750V PVC insulated cables, and IEC2271; IEC2272; IEC2273; IEC2274; IEC2277 related technical indicators and requirements.

B. main and sub cable should be in line with the user specified specifications, models, section requirements.

2) cable hanging head is as prefabricated branch cable in vertical installation of lifting rack, prefabricated branch cable accessories, in level arrangement, without the attachment.

Technical requirements:

A. AC.3500V, 5min tolerance does not appear breakdown; the insulation resistance is greater than or equal to 200M. B. bear the weight of the prefabricated branch cable 2 times the gravity 24h does not fall off. Because the prefabricated branch cable is fixed, the hanging head is no longer under gravity.

3) technical requirements for outer sheath and inner insulation of main and branch cables:

A. confirm user specified length size;

B. cut off the outer sheath of the main branch cable, the inner layer of the insulation of the cut neatly, and less damage to the conductor of the cable material.

4) the technical requirements for the suppression of the branch joint:

A. connection parts should meet the technical requirements of the standard;

B. after pressing and forming the branch connector should have enough pressure relay, contact area, to ensure that the contact resistance is approximately equivalent to the length of the conductor resistance;

The conductor material which is not allowed to damage the main and branch cables is not allowed during the C. compression process;

5) the technical requirements for the injection molding of the branch joint:

A. injection molding insulation material should be used with the main, sub cable layer insulation or outer sheath of the same type of insulation material;

B. in the injection molding process shall not be on the main, sub cable of the original inner insulation and outer sheath to cause any damage;

C. to ensure that the injection molding material and the main and sub cable outer sheath effective viscosity after the whole of the air tightness and water tightness;

The D. branch of CIS after injection molding, pressure AC.3500V, 5min no breakdown; the insulation resistance is greater than or equal to 200M.

6) finished product inspection of branch cable

A. appearance check;

Continuity test for B. main and branch cables;

C. withstand voltage test;

D. insulation resistance test.

7) finished product packing of prefabricated branch cable

The prefabricated branch cable is sealed with a cable cap for each cable end when the package is packaged, and then is wound on the cable tray or in the form of a bundle.
