Abstract:
An electric conductor may be provided. The electric conductor may comprise a conductor core and a plurality of conductor strands wrapped around the conductor core. The conductor core may comprise a plurality of core strands comprising an overall number of strands. The plurality of core strands may comprise a first portion of core strands and a second portion of core strands. The first portion of core strands may comprise a first number of strands. The first portion of core strands may comprise steel. The second portion of core strands may comprise a second number of strands. The second portion of core strands may comprise a composite material. A ratio of the first number of strands to the overall number of strands and a ratio of the second number of strands to the overall number of strands may be optimized to give the conductor core a predetermined characteristic.
Abstract:
A cable pull calculator may be provided. First, wire number data, a wire type, and size data may be received. Next, a minimum conduit size for the conduit maybe calculated based upon the received wire number data indicating the number of wires to be placed in the conduit and the received size data corresponding to each of the wires to be placed in the conduit. Then, the calculated minimum conduit size may be displayed. Next, a first desired conduit size, a conduit type, and pull information indicating a course of the conduit may be received. Then, for each of the plurality of segments, a tension value and a sidewall pressure value may be calculated based at least on the conduit type, the first desired conduit size, the received wire type, and the received size data. The calculated tension value and the calculated sidewall pressure value may then be displayed.
Abstract:
Disclosed is type THHN cable having a reduced surface coefficient of friction, and the method of manufacture thereof, in which the central conductor core and insulating layer are surrounded by a nylon sheath. A high viscosity, high molecular weight silicone based pulling lubricant for THHN cable, or alternatively, erucamide or stearyl erucamide for small THHN gauge wire, is incorporated, by alternate methods, with the nylon material from which the outer sheath is extruded, and is effective to reduce the required pulling force on the cable during installation.
Abstract:
Real-time power line rating may be provided. First, sensor data may be received corresponding to a conductor of a power line. The sensor data may provide real-time weather conditions for the conductor's environment. The sensor data may be received from a sensor device configured to collect the sensor data. The sensor data may correspond to the weather conditions at a location of the sensor device on the power line. Next, design limitations for the power line having the conductor may be received. The conductor of the power line may have a design ampacity based upon the design limitations and assumed weather conditions for the conductor's environment. Then a dynamic ampacity may be calculated for the power line based upon the received sensor data and the received design limitations for the power line. The power line may then be operated according to the calculated dynamic ampacity instead of the design ampacity.
