UL1007 wire is dual rated with UL1569 which are both approvals given by Underwriters Laboratories.
Companies that manufacture UL1007 / UL1569 wire test the insulation to the maximum amount, however having a 3rd party that also tests and approves the wire for 300 volts and 105°C gives the end-user a more secure feeling that it will perform the same at its maximum voltage and temperature rating. Therefore, the UL style numbers have become very popular in the hookup wire industry.
UL1007 is also known as a PVC 300 Volt lead wire, appliance wire, hook up wire, electronic lead wire, and more. Any of these terms can be used to describe your particular single conductor wire so make sure you look at the attributes that each type has to offer. For instance, UL1015 wire is rated for 600 volts but can also be described as all of the terms just mentioned. Look at the voltage and temperature rating to make sure it can handle your applications environment.
3 Most Common Types of Hook-Up Wire
1. UL1007 wire: 300 volts, 105°C, PVC insulation for indoor appliances, and electronics.
2. UL1015 wire: 600 volts, 105°C, PVC insulation for indoor appliances, and electronics.
3. Type E wire: 600 volts, 200°C, PTFE insulation for high-temperature indoor applications.
Each type of hook up wire has slight differences for each different application. Make sure you ask your wire and cable supplier questions so that you understand what you’re buying and know that it can last in the application you have.
Striping & Tin Dipping 300 Volt PVC Hook-Up Wire
For low voltage and low current applications, hook up wire is the most appropriate connectors to be used. Low voltage refers to a voltage range below 1000 volts that is common for enclosed electrical equipment that can be found commonly at home and in the office. To name a few commonly encountered applications, hookup wires can be found in computers, control panels, business machines (facsimile, photocopy machines, laminating machines), appliances, and electronic meters.
Most of the time, the lead wires are available for purchase with insulation made of rubber or thermoplastic materials that are sometimes rendered to be insufficient protection against factors that can bring greater damages. These insulations include the following: polyvinyl chloride (PVC), polyethylene (PE), silicon rubber, polypropylene, neoprene, and propylene diene elastomers that are not resistant to high levels of heat. These materials are made of polymers that usually break and melt upon being subjected to temperatures beyond their respective threshold levels. As a result, many users of hookup wires resort to striping and tin Dipping hook up wire as the most viable solution for such problems.
The first step in having a Striping and Tin Dipping Hookup Wire is striping. Striping can be done easily. One does not need to be knowledgeable of the electronics basics in order to do execute this rather simple task. The procedure can even be done at home. There are wire strippers that are available in any hardware store; it would be helpful to get one instead of using a pair of scissors, a cutter, or a pocket knife. Once you have a wire stripper, it is important to employ the proper technique in striping the wire. While taking off the insulator, make sure to apply just enough force in order to avoid breaking or nicking the metal conductor inside. Nicking or breaking the wire would render the effort useless, you might end up buying a new one. In removing the insulation with the stripper, make sure to be gentle in rocking it back and forth followed by a swift motion of pulling the sheathing away.
Tin dipping is the final step in order to make sure the strands won’t fray upon delivery of the product. Professional help is needed in this case because it involves melting tin at a very high temperature. The hookup wire is dipped in a molten tin bath at a temperature greater than 450 degrees Fahrenheit (or 252 degrees Celsius). Due to tendencies of metallic bonding, two layers are formed: the interface that is a mix of the base material and the tin and a layer that is made of pure tin.
Several benefits can be reaped from tin dipping the 300-volt hookup wire, namely: prevention of rusting and oxidation and the capability to be subjected to soldering. In addition, the resulting material is nontoxic and it effectively resists wearing and corrosion. However, the coating thickness is difficult to control. Despite this disadvantage, it can be seen that the pros outweigh the cons, thus making this a widely applied process. Lastly, tin dipping is compliant with the standards set for use of elements in electronic products that may be hazardous to people and the environment.
