Surface electrical resistance of cable sheath
Did you know?
WebA metallic sheathed cable is a type of electrical cable that is made from a metal sheath that covers the inner conductor. The sheath provides a barrier between the conductor and the environment, making the cable more resistant to environmental factors. The cable is also less likely to corrode and is less likely to cause voltage drops. WebSheet resistance is a special case of resistivity for a uniform sheet thickness. Commonly, resistivity (also known as bulk resistivity, specific electrical resistivity, or volume resistivity) is in units of Ω·m, which is more completely stated in units of Ω·m2/m (Ω·area/length).
WebThese low level currents can degrade the cable sheath from a hydrophobic to a hydrophilic state, which increases the likelihood of surface electrical discharge phenomena such as corona or...
