Cables by Type
Construction
● Conductors: Made of 1350-H19 alloy wires, which can be Aluminum Alloy Conductor (AAC) or Aluminum Conductor Steel Reinforced (ACSR). The wires are arranged concentrically for effective conductivity and strength.
● Insulation: A uniform layer of cross-linked polyethylene (XLPE) is used for insulation, offering excellent protection against environmental factors and ensuring high electrical performance.
● Additional Features: A layer of semiconductor material is applied to the metallic conductor to further enhance electrical performance.
Standard
ABNT NBR 11873
1. Title: Cables coated with polymeric material for distribution of air power in fixed spacers, at voltages of 13.8 kV to 34.5 kV
2. Scope: ABNT NBR 11873 is a Brazilian standard for medium voltage ecological cables made with aluminum conductors. These cables are designed for use in medium voltage power distribution networks and are recognized for their environmentally friendly construction. The standard outlines specifications for materials, construction, and performance to ensure the cables are durable, safe, and efficient in various environmental conditions. This includes resistance to UV radiation, chemicals, and mechanical stresses, making them suitable for harsh outdoor environments
