What Exactly is Primary Wire?

Posted by Andrew on Jan 18, 2016 10:07:00 AM

Primary wire is primary wire, right? Not exactly true. There are different “grades” of primary wire, based on temperature ratings (voltage ratings are typically the same at 50V DC). Buy the wrong type, you could wind up melting the jacket and causing a short or electrical fire. Not good at all. So let’s go over some basics.



Generally, standard primary wire is the most popular, widely used and economical type of wire. The insulation jacket is normally smooth and brightly colored and is manufactured from PVC (polyvinyl chloride).

HDT – Heavy-Duty Thermoplastic and TWP – Thin wall Thermoplastic primary are also available, but I will be focused on the standard wire.

The internal copper strands of standard primary wire are bare copper (BC) and gauge size of the wire is measured to SAE standards. Stranding is often represented by 7/.0126. The first number is

Choosing the Right Heat Shrink

Posted by Steve on Dec 28, 2015 10:51:00 AM

Del City offers a wide selection of heat shrink to ensure your wire and connections are protected from dirt, moisture, and corrosion. Heat Shrink is commonly used in applications where the connection is exposed to corrosive environments such as battery connections, marine panels, and trailer wiring. The heat shrink allows for the connection to be “sealed” off from salt water, road spray and debris, as well as dust and dirt.

Choosing the Right Type

The most basic choice is a 2:1 single wall non adhesive heat shrink tube. It is a good all around, general purpose product and is available on rolls as well as 4’ sticks. This style of heat shrink is most often used in general purpose applications particularly where the connection is not exposed to a lot of contaminants. In addition, this product is a UL recognized component.

The most popular option is

Is a Ratcheting Crimp Tool Worth the Extra Money?

Posted by David on Dec 11, 2015 11:03:00 AM

A few weeks ago, Del City exhibited at the SEMA Show for our 28th consecutive year. I always enjoy going to the show to see all the exotic vehicles and innovative new products but what I enjoy most about the show is talking to both prospective customers as well as customers that have been ordering from Del City for more years than they care to mention. It’s great to hear about all the diverse applications our products are being used in as well as the most efficient way people are using our items.

One topic that I received more questions on this year than most was surrounding ratcheting crimp tools compared to a standard crimp tool. Those I talked to wanted to know if it’s really worth the extra money to invest in a ratcheting crimp tool over a standard crimp tool.
