TECHNICAL NEWS
The maximum sidewall pressure that modern cables can withstand without causing incipient damage is based on the number of cables pulled together and the size of the conductors.
MAXIMUM SIDEWALL PRESSURE
Sidewall Pressure (SP) is the radial force exerted on a cable as it is pulled around a bend. Excessive sidewall pressure can cause cable damage and is the most restrictive factor in many installations.
