Braided Forissier Braided Copper Strip Selection Guide

Common problems and troubleshooting

Possible causes and solutions for the problem phenomenon

Connector overheating (>85 ° C bare copper) with insufficient current carrying capacity; The parallel coefficient has not been taken into account; If the ambient temperature is higher than expected, recalculate the current carrying capacity, increase the number of parallel connections or choose a larger cross-section; Improve ventilation

Local high-temperature contact surface oxidation at the terminal; Loose bolts; The drilling size does not match the clean contact surface, apply conductive paste; Tighten again according to the torque; Check if the gasket is flattened

Micro motion wear caused by broken wires in woven tapes due to electric force; Excessive bending during installation is achieved by weaving fine threads (0.10 mm) to enhance flexibility; Increase mechanical reinforcement; Adjust installation angle

Surface corrosion (green or black) caused by corrosive gases in the environment; If the coating fails, use 15 μ m tin plating or silver plating instead; Replace with nickel plated or gold-plated terminals

Uneven current distribution in parallel connectors and differences in braided tape length; The terminal contact resistance is different; Ensure that the length of each connector is consistent when the spacing is too small; Use the same tightening torque; Increase spacing

Quick selection process

To help engineers quickly complete the selection process, please follow these steps:

Determine the required total current carrying capacity Itot (A) and ambient temperature Tamb (° C).

Determine whether to parallel: If Itot>maximum current carrying capacity of a single unit (such as 2000A), parallel connection is required.

Estimate the number of parallel connections n (usually 2-8).

Calculate the required current carrying capacity for a single unit, I2=Itot/coefficient (n) (refer to Table 2.3 for the coefficient).

Refer to Table 2.2: Find the minimum cross-section of ≥ I2 single in the corresponding ambient temperature and conductor type (bare copper/tin plated) column.

Confirm terminal size: Based on the selected cross-section, determine the recommended terminal A × B and drilling type from Table 3.2.

Confirm if special treatment is required: angled terminals, mechanical reinforcement, special coatings, etc.

Prepare order code: Forissier order code format is CSTP1000MMCRELT500, where:

CSTP: Tin plated copper (CSTN is bare copper)

1000: cross-sectional area mm ²

MMC: Terminal length 100mm, etc. (customized)

RELT500: Customer parameters such as center distance. Suggest providing complete drawings.
