Description

Technical Field

[0001] This utility model belongs to the field of live-line working tool testing technology, and in particular relates to a portable tensile testing device. Background Technology

[0002] Insulating ropes for live-line working refer to insulated ropes used for live-line work on electrical equipment of various AC and DC voltage levels. Insulating ropes for live-line working can be classified as follows: 1. By material: natural fiber insulating ropes, synthetic fiber insulating ropes; 2. By electrical performance: conventional insulating ropes, moisture-proof insulating ropes; 3. By mechanical strength: conventional strength insulating ropes, high strength insulating ropes; 4. By manufacturing process: braided, stranded, interlaced insulating ropes.

[0003] Precautions for using insulating ropes: First, check for damage, breakage, or tearing; second, check for dampness or mold; third, check for a decrease in tensile strength. If any of the above phenomena are present, a tensile test must be performed; otherwise, do not use the rope to prevent safety accidents.

[0004] Insulating ropes require periodic mechanical testing to check for any decline in tensile strength. The relevant regulations are as follows: 1. Cycle and Test Items: Test cycle: 24 months. Test item: Static tensile test. 2. Requirements: The tensile strength of the personal and electrical wire insulating ropes should remain undamaged and unbroken for 5 minutes at the values ​​listed in Table 19. The tensile strength of the personal and electrical wire insulating ropes is shown in Table 1.
