What is single wire ?

 

The term “single core wire” is often heard, but what exactly is it? Let’s explore this ubiquitous component, present in almost every aspect of our lives, from its definition and applications to its advantages.

A single core wire is an electrical wire consisting of a single conductor encased in insulation. The conductor is typically made of bare copper or copper plated with tin, silver, or nickel. The insulation is commonly made of PVC, but other materials can also be used. The conductor structure can be stranded or solid copper, depending on customer requirements.

From simple circuits to complex telecommunication systems, from high-tech products to simple electronic devices used in our daily lives, single core wires are indispensable. The primary difference between single core wires and multicore cables lies in the number of conductors used.

 

UL Standard Single Core Wires

 

UL 1015 – Single Core PVC Insulated Wire

Description: Wires using PVC as insulation material are suitable for use in dry locations.

Applications: UL1015 hook-up wires are suitable for use in control circuits, appliances, and other electrical equipment.

 

UL 1007 – Single or Stranded PVC Insulated Wire

Description: Like the 1015, UL 1007 wire also uses PVC as its insulation material. However, 1007 is designed for use in low voltage environments and is more flexible.

Applications: Its flexibility makes it often used for internal wiring of appliances and electronic equipment.

 

UL 1569 (Single Conductor)

Description: As the name suggests, a single conductor is composed of a single conductor, using a single or stranded 30~10AWG tinned or bare copper. This conductor is flat and flexible, with less restrictions on the use of space.

Applications: Commonly found in electronic equipment, automotive applications, and other specialized uses.

European Standard Single Core Wires

 

1. H07V-U (PVC Insulated Wire)

Description: This is a single-core wire with PVC insulation that can be used in both dry and damp environments.

Applications: Often used in lighting and power circuits.

 

H05V-U (PVC Insulated Wire)

Description: Similar to H07V-U, this is a single-core wire with PVC insulation, but this one is specifically designed for low voltage applications.

Applications: This wire is flexible and suitable for indoor appliances, lighting and other wiring applications.

FRNC (Flame Retardant, Non-Corrosive) Single Core Wire

 

Description: FRNC is known for its fire resistance. It produces very little smoke when the wire catches fire, leaving people more time to escape. It is often used in areas where safety measures need to be strengthened.

Applications: Commonly used in emergency lighting, alarm systems, and other critical installations.
