Guarded coaxial cable assembly

An assembly for guarding an electrical cable comprising:

• the electrical cable including a conductor within an insulating sheath;
• a first metallic rail extending alongside the electrical cable;
• an outer jacket that envelops the first metallic rail and the electrical cable;
• the jacket having a generally rectangular cross-section with two opposed wide sides and two opposed narrow sides;
• the opposed wide sides form opposed wide bearing surfaces for bearing transverse loads;
• an orientation of the first metallic rail and the electrical cable within the jacket configured to limit deformation of the electrical cable resulting from one or more transverse loads applied to the opposed wide bearing surfaces;
• and,
• the assembly undergoes bends of 90-degree or more as the assembly is squeezed between a sash and a mating U shaped jamb such that the opposed wide bearing surfaces are subjected to the transverse loads.
