Cables by Type

Protected Aluminum Cable

Medium Voltage Protected Aluminum Cable, also known as cable aluminio protegido media tensión or conductor aluminio protegido in Spanish, is specifically designed for use in compact primary medium voltage energy distribution networks. Its construction ensures resistance to environmental and mechanical stresses, making it an ideal choice for overhead distribution networks in various settings. The protective layers and semiconductor materials used in these cables offer enhanced electrical insulation and durability, ensuring a consistent power supply with reduced maintenance needs.

It is designed for voltage ratings of 15kV, 25kV, and 35kV, ensuring suitability for various distribution network configurations and engineered to resist chemical degradation, UV radiation, and oil exposure, maintaining performance integrity in diverse environmental conditions, featuring a minimum bending radius of 10 times the cable diameter, providing flexibility without compromising structural integrity.

Construction

● Conductor: 1350 aluminum wires, compacted in class 2 cording, and equipped with longitudinal moisture blocking, compliant with NBR NM 280 standards.

● Semiconductor Layer: Use thermoset material (XLPE) or thermoplastic (PE), with optional application for 15kV and 25kV cables and mandatory for 35kV cables, ensuring optimal electrical insulation.

● Protective Layer: It consists of one or two layers of thermoset material (XLPE) or two layers of polyethylene (LDPE/HDPE or XLPE/HDPE).

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
