skills requirement:
a: Withstand AC.3500V, no breakdown occurs for 5min; insulation resistance ≥200MΩ.
b. Withstand the gravity of the prefabricated branch cable 2 times the weight of 24h does not fall off. After the prefabricated branch cable is installed and fixed, the hoist is no longer subjected to gravity.
Technical requirements for stripping the outer sheath of the main and sub-cables and the inner insulation:
a. Confirm the user specified length size;
b. Cut and peel the outer sheath of the main sub-cable, the inner insulation of the incision should be neat, and less than the conductor material of the cable.
Technical requirements for press-forming of branch joints:
a. Connector joints should meet the requirements of technical standards;
b. The crimped joints shall have sufficient crimping force and contact area to ensure the contact resistance is approximately the equivalent length of the conductor;
C. It is not allowed to damage the conductor materials of the main and sub-cable cables during the crimping process;
Technical requirements for injection molding of branch joints:
a. Insulation materials for injection molding shall be of the same insulation type as the inner or outer insulation of the main and sub-cables;
b. During the injection molding process, no damage shall be caused to the original inner insulation and outer sheath of the main and sub-cables;
c. Ensure the airtightness and watertightness of the injection molding material and the outer sheath of the main and sub-cables after effective adhesion;
d. After the injection molding of the branch joint, the breakdown voltage does not occur under the AC.3500V, 5min; the insulation resistance is ≥200MΩ.
Finished inspection of prefabricated branch cables:
a. visual inspection;
b. continuity test of main and branch cables;
c. Withstand voltage test;
d. Insulation resistance test.
Finished packaging of prefabricated branch cables:
The prefabricated branch cables are sealed at the end of each cable with a cable cap, then wound onto a cable drum or bundled and packaged in a suitable manner that will not damage the cable during transport. Http://news.chinawj.com.cn
