Comparing Wires to Wires: UL 1007 VS UL 1015

Comparing wires to wires

UL 1007 VS UL 1015

In today’s blog, we’d like to get a bit more technical and specific into two types of wires, their specs and how they compare and contrast. For the past months, here at Z-Tronix, we have been cooking up a special segment called, ‘Comparing Wires to Wires’ with the end objective of informing engineers, company buyers/purchasers, hobbiests and anyone interested in wires and cables about the versatility wires and cables might have, to the point where they might end up overlapping and being able to serve same purposes in emergency situations.

The wires responsible for inaugurating ‘Comparing Wires to Wires’ have much in common but there are critical differences that are noticeable in terms of performance under pressure. UL 1007 and UL 1015 are two wires that are similar; they not only both have PVC insulation, and single conductors but also come in solid or stranded conductor type, tinned, bare copper, topcoat and prebond conductor metals. In terms of temperature, although UL 1007 is very limited with only one option of 80°C and 300V, UL 1015 overlaps with 80°C and has wire configurations of 90°C, 105°C and voltage of 600V making it a suitable alternative to UL 1007.

In UL 1007 wire, the conductor in solid or stranded form can be bare copper or coated with topcoat, prebond or tinned copper. While the 0.38 mm PVC thickness allows for easeful use in smaller electrical and electronic devices, the gauge sizes can be seen ranging from 32 AWG to 16 AWG with a temperature and voltage of 80°C and 300V, respectively. This Z-Tronix UL 1007 wire has passed not only the UL VW-1 Flame Test but is also compliant with CSA Style TR-64, RoHS. This wire can be typically used as internal wiring for electronic and electrical equipment applications.

In UL 1015 wire, the conductor solid or stranded form can be usually found in top coat, tinned or bare copper; allowing the 0.76 mm PVC thickness to be used best in appliances as well as in wire harnesses and cable assemblies where risk of oil may be present. UL 1015 can be typically found in gauges ranging from 28 to 10 AWG with a temperature of 80°C, 90°C and 105°C as well as a voltage of 600V. This Z-Tronix  UL-1015 wire has passed the UL VW1  and CSA FT1 Flame Tests. This wire can be typically used as internal wiring for appliances.

It’s evident that the most obvious difference between both wires is the thickness of the wire insulation. For this reason, most buyers who know their voltage and temperature rating and prefer a thicker insulation might end up opting for UL 1015. Along the same line, another difference is the adaptability/versatility of this type of wire. Common hook up wire tend to have the ability to meet other UL ratings and UL 1007 and 1015 are not the exception. UL 1007 wire fulfills UL 1569 as well as CSA TR-64 while UL 1015 wire can fulfill UL 1230 and UL 1426. 

Regardless of being single conductor and PVC-insulated, both differ by a lot. Voltage, temperature and conductor type modify performance so knowing the versatility can and will assist in the decision making of your type of wire.
