The Broadwell cable harness reinforces the fabric envelope, taking stress off of the fabric and increasing its safety factor. In fact, fabric reinforced with a cable harness experiences only 7% of the forces that fabric without a harness experiences. This lengthens the useful life of the fabric envelope.
Pulleys adjust the cable harness system as forces act on the dome, thus constantly maintaining even force distribution. Other domes that have only a few cables to reinforce the fabric do not distribute forces evenly, and don’t provide any reinforcement to the fabric corners of the dome. A major reason Broadwell has a perfect safety record is due to the extra safety and durability that the cable harness provides.
