Final answer:
Conductor pulling tapes help minimize friction between the cable and conduit, in addition to their purpose of pulling in conductors or ropes. They are coated with a special low-friction substance to fulfill this role.The correct option is option d.
Step-by-step explanation:
The question is asking what additional purpose conductor pulling tapes serve besides pulling in conductors or ropes. Out of the given options (a. lubrication, b. measurements, c. proofing, d. friction), the correct answer is d. friction. Conductor pulling tapes are intended to reduce the amount of force needed to pull cables through conduits and are designed to minimize friction between the cable and the conduit. To enhance this characteristic, pulling tapes may have a special low-friction coating.
Considering the information related to friction and electrical resistance, it seems the question is connected to the broader concepts of physical and electrical forces at play in practical applications. For example, the force of friction plays a crucial role in the physical pulling of cables, while electrical resistance can be conceptualized as friction in the context of electrical flow, affecting energy loss and heating in electrical systems.
Moreover, the question also touches upon static electricity, which involves the transfer of charge. This is not directly related to the primary function of cable pulling tapes, but it is an interesting aspect of how certain materials can become charged and exert electrostatic forces, as in the case with common tape becoming charged when pulled from a dispenser as mentioned in the provided information.
