# Production and application skills of parallel wire and stranded wire

## Introduction In power engineering and electrical installation, the merging of wires and the production of stranded wires are a crucial part. Reasonable parallel wire and stranded wire can not only improve the safety and stability of the circuit, but also improve the construction quality of the overall project. This article will elaborate on the production techniques, application scenarios and precautions of parallel and stranded wires, hoping to provide valuable reference for relevant practitioners.

## The production skills of 1. parallel line ### 1.1 The basic concept of parallel line is to connect two or more wires side by side to form a whole, so as to jointly undertake the task of current transmission. In the decoration and electrical installation, the parallel line is often used to increase the load capacity of the circuit or to realize the parallel connection of multiple circuits.

### 1.2 Production Steps#### 1.2.1 Preparation Tools and Materials The tools to be prepared for parallel production mainly include wire stripper, vice, electrical tape, etc. The materials include wires to be parallel and connection terminals or connectors that may be required.

#### 1.2.2 Stripping First, use the wire stripper to strip the insulation of the wire to expose a certain length of the metal core. Be careful not to damage the wire core when stripping the wire, and ensure that the length of the stripped insulation is appropriate for subsequent operations.

#### 1.2.3 Parallel wire Place the wire cores with the insulation stripped away side by side to ensure close contact between them. For the merging of multiple wires, the "twist" winding method can be used, that is, the adjacent wire cores are alternately wound together to increase the contact area and firmness. Winding should pay attention to uniform strength, avoid too tight or too loose.

#### 1.2.4 Fixation and insulation After the parallel line is completed, use vise or other tools to fix the parallel line part to prevent loosening. Subsequently, the parallel part is tightly wrapped with electrical tape to ensure good insulation and prevent leakage and short circuit.

### 1.3 Parallel Artifact In order to improve the parallel efficiency, parallel artifact has also appeared on the market. This kind of tool usually combines an electric drill and a parallel wire mold, which can automatically complete the parallel wire and insulation treatment of the wire, which greatly improves the work efficiency and the parallel wire quality. When in use, just put the wire into the parallel mold and start the electric drill to complete the parallel operation.

## The production skills of 2. stranded wire### The basic concept of 2.1 stranded wire is stranded wire, that is, a process in which several single wires are twisted together according to certain directions and rules to form an integral core. Stranded wire has the advantages of good flexibility, high reliability and high strength, and is widely used in power transmission and electrical installation.

### 2.2 Manufacturing Steps #### 2.2.1 Select Single Wire According to the specifications and requirements of stranded wire, select the appropriate single wire. The material, diameter and quantity of the single wire will directly affect the performance of the stranded wire.

#### 2.2.2 Stranding The selected single wires are twisted together according to certain directions and rules. During the stranding process, attention should be paid to the control of the stranding pitch and the stranding direction to ensure the flexibility and stability of the stranded wire. At the same time, the close contact between each single wire should be maintained during stranding to avoid voids and looseness.

#### 2.2.3 Tightening and Shaping For stranded wires that need to be compacted, compacted processing is also required. Tight compression can increase the filling factor, reduce the geometric size of the conductor, and improve the conductivity and mechanical strength of the stranded wire. After pressing, it needs to be shaped to ensure that the shape and size of the strand meet the requirements.

### 2.3 stranded wire type and application stranded wire according to the different materials and uses, can be divided into many types, such as aluminum stranded wire, hard copper stranded wire, steel core aluminum stranded wire, etc. Different types of strands have different application scenarios in power transmission and electrical installations.
