Line Guard protects overhead power and telecommunication conductors from physical damage such as bending, compression, and abrasion at support points. It reduces outage risks and maintains line integrity by addressing wind sway, unbalanced loading, and environmental exposure. Constructed from high-strength aluminum alloys and polymers like Acrylonitrile Butadiene Styrene (ABS) plastic or polypropylene, the guard resists moisture, corrosion, and Ultraviolet (UV) radiation while withstanding harsh weather conditions.
Line Guard restores full conductor strength when less than 50% of outer strands are damaged and provides protection against abrasion and arc-over. High visibility enables quick identification, while uniform material construction ensures consistent performance. Special ends eliminate corona effects in high-voltage applications. Available sizes accommodate conductor diameters from 0.182 to 0.898 inches with color-coding for rapid identification. Models are rated for 46 Kilovolt (KV) or 69 KV, tested to American Society for Testing and Materials (ASTM) standards, and handle conductors up to 1272 thousand Circular Mils (MCM).
Use Line Guard for hand-tied spans under 300 feet and repairs where no more than 25% of outer strands are damaged outside support areas. Installation involves aligning center marks and using tools like shotgun hot sticks, then pulling downward and rotating into place. Product variants include single and double support lengths, various rod diameters, and multiple color codes, with options for animal deterrence featuring roller systems.

Perguntas Frequentes (FAQ)
O que é um guarda de linha e contra o que protege?
Os guardas de linha protegem os condutores reduzindo a flexão, a compressão e o desgaste nos pontos de fixação. Eles impedem descargas elétricas e danos por abrasão, e oferecem capacidade limitada de reparo, especialmente em locais onde são utilizadas amarras manuais.
Quais tipos de condutores são compatíveis com protectores de linha?
As proteções de linha são fabricadas para condutores ACSR, AAC, AAAC, ACSS, SSAC, tipos TW e ACAR, atendendo tanto a configurações de alumínio quanto de cobre.
Para quais aplicações de tensão os protectores de linha são adequados?
Os guardas de condutores são adequados para aplicações de alta tensão, incluindo classificações de 46 kV e 69 kV. Para 345 kV e acima, os finais especiais são modificados para eliminar os efeitos corona.
How does the color coding system assist with installation?
Line guards feature color-coded centers that correspond to conductor size, facilitating quick identification and proper alignment of rods during installation.
Can line guards restore damaged conductor strength?
When no more than 25% of outside strands on an ACSR or aluminum conductor are damaged outside the support area, line guards can restore 100% of rated conductance and strength. They should not be used for repair at the support point itself, and are recommended for spans under 300 ft (91 m).
