Hola colegas:
Estoy traduciendo un artículo que habla sobre cables de alta calidad para aplicaciones industriales, y estoy en duda con este subtítulo:

Exterior outer jacket. Mi intento es: Cubierta exterior (para exteriores? queda un poco redundante y no sé si es el término correcto)

Este es el contexto:

Exterior outer jacket
The outer jacket material and thickness are crucial for the long life of industrial cables. The thicker the outer jacket, the better protected the cable.

The cable’s outer jacket in industrial environments needs to handle many forms of harsh abuse that can quickly degrade the cable. Sunlight, particularly ultraviolet (UV) light, can cause outer jacket discoloration or cracks. Solvents including oil, gasoline, and cleaning chemicals can also dissolve the outer jacket leading to failures. High temperatures can lead to shortening of the cable, which becomes more of a liability over longer cable lengths. Extreme cold temperatures can cause the outer jacket to become brittle, leading to visible cracks that may result in the outer jacket shedding and breaking off.

The outer jacket must also be able to handle physical abuse such as the abrasive effect of pulling the cable around sharp corners. The wrong outer jacket can lead to openings in the cable revealing the shielding or conductor wires. Thick polyurethane is a reliable choice of outer jacket material for high quality cables because of its resistance to abrasion. Polyurethane is also resistant to solvents, temperature, light exposure, and abuse of all kinds.

Desde ya les agradezco sus sugerencias.
