A coaxial cable consists of a single conductor surrounded by a shield (Figure 2-54a), while a triaxial cable adds a second shield around the first (Figure 2-54b). With triax cable, the inner shield can be driven at guard potential in order to reduce cable leakage and minimize circuit rise times. The outer shield is usually connected to chassis ground or, in some cases, to the common terminal. In either case, the outer shield must not be allowed to float more than 30Vrms (42.4V peak) above chassis ground for safety considerations. Always use a cable with a tightly woven shield to protect against electrostatic interference.
