Rating | 60 deg C, 300 Vac. |
|
Conductor | Six tinsel threads stranded with rope lay around a No. 10 three-ply cotton thread at nominally 2.5 turns per inch. Each tinsel consists of two 37 AWG flattened conductor strands to nominal 0.0009 by 0.018 inch and spiraled concentrically around a core of No. 20, three-ply cotton threads. The conductor resistance per linear foot of cord length shall be 0.28 ohms maximum. |
|
Insulation | Extruded SRB/NR, 15 mils minimum average thickness, 13 mils minimum thickness at any point. |
|
Assembly | Three conductors, same as type SV Cord, but with a lay of twist opposite in direction to the direction in which the helical cord is wound. |
|
Jacket | Extruded Neoprene, 30 mils minimum average thickness, 24 mils minimum thickness at any point. The cord is vulcanized while coiled in a helical shape on a mandrel. When the helix is stretched out and released, the cord returns to its helical form because of the elasticity of the jacket. |
