Abstract
The project requires the supply of various materials, including aluminum conductor steel reinforced (ACSR) cables, compression splices, and pre-stressed steel, concrete poles. The poles are designed to withstand nominal forces ranging from 400-kgN to 2,400-kgN, depending on the length and type of pole. The project also includes the installation of secondary transformers, which are rated at 25-kVA, 40-kVA, 63-kVA, 100-kVA, 160-kVA, 250-kVA, 400-kVA, 630-kVA, and 1,000-kVA. The transformers are oil-immersed and have a dual voltage rating of 15-20/0.4-kV. In addition to the transformers, the project requires the installation of distribution panels, circuit breakers, and revenue meters. The distribution panels are rated at 400-V and have a compact design with copper bus bars and circuit breakers. The revenue meters are rated at 30-A and have a kWH rating. The project also involves the installation of 400-V OHL to meter boxes, which are made of air-bounded conductor (ABC) materials such as aluminum, AAC, ACSR, and AAAC. The OHL is rated at 0.6/1-kV and has a length of 2,250 meters. The project requires the supply of various materials, including guy wires, guying cone anchors, and guying anchor rods. The guy wires are made of zinc-coated steel and have a diameter of 7x2.00-mm (7.0-mmΦ) or 7x3.65-mm2 (11.0-mmΦ). The guying cone anchors are made of concrete and have a diameter of 200-mm. The project also involves the installation of service laterals and SE disconnects, which are made of copper NYY 3x6-mm2 RE or 3x10-mm2 RE. The service disconnects are rated at 30-A and have a metal enclosed circuit breaker or a plastic enclosed circuit breaker. The total quantity of materials required for the project is not specified in the document. However, the document provides a detailed breakdown of the materials required for each component of the project.
