Relative Costs

CABLE CONSTRUCTION
Fewer number of wires in a cable will result in lower cost and less flexibility. Hence, a 1x19 (19 wires) will be less expensive than a 7x7 (49 wires) and a 7x7 will be less expensive and less flexible than a 7x19 (133 wires) in the same diameter.

MATERIAL
Stainless steel cable using standard 302/304 stainless, will cost approximately 1.5 to 3 times more than galvanized steel cable, depending on the size and construction. Galvanized steel cable with a plastic coating will generally cost less than stainless steel cable, particularly in sizes over 3/32˝. Vinyl coating is less expensive than nylon, and FEP is the most expensive. Contact factory for other types of cable and coating materials available.

STRENGTH RECOMMENDATIONS
Specifying less than full strength on your cable assembly prints will usually result in lower pricing, usually accomplished by crimping the fitting over the cable coating (a loss of strength of approximately 35%). However, to obtain full breaking strength, the cable coating would then be stripped and the fittings swaged directly onto the cable. Also note that cables with 1X19 construction have less holding strength, consult factory.

LENGTH TOLERANCES
Length tolerances are an important cost consideration. Close tolerances require more expensive cutting processes and increased inspection criteria. Cable sizes and fittings used often determine attainable tolerances. Assemblies specifying precision tolerances must state under what load the length is to be measured. Please, do not overspecify. Confirm with SAVA Industries, your desired tolerances prior to production. Standard tolerances will be used unless otherwise agreed upon.

FITTINGS
The following is a ranking of the relative cost of fittings starting from the least expensive. The ranking is predicated on the cost of the fitting and its cost of attachment to the cable based on the assembly being manufactured by SAVA INDUSTRIES, INC. :
EYE, BALL-END PLUG, BALL, THREADED PLUG, BALL & SHANK, LOOP, MS TERMINALS.
