1. Product Overview

2. Core Features

(1) Copper Conductor

• The wire is made of high-quality copper, which is renowned for its excellent electrical conductivity. Copper has a low resistivity, allowing for efficient transmission of electricity with minimal energy loss. This ensures that electrical power is delivered effectively to the intended devices or circuits, reducing the risk of overheating and improving the overall energy efficiency of the electrical system.

(2) Single Core Design

• The single core structure makes the wire easy to install and route. It is flexible enough to be bent and shaped according to the specific layout requirements of the construction site. This flexibility simplifies the installation process, especially in tight spaces or when making connections to various electrical components. Whether it's for connecting switches, sockets, or other electrical fixtures, the single core design provides convenience and ease of use.

(3) PVC Insulation

• The wire is insulated with PVC (polyvinyl chloride), which offers several important properties. PVC provides good electrical insulation, preventing the flow of current to unintended areas and reducing the risk of electric shock. It is also resistant to moisture, chemicals, and abrasion. This insulation layer protects the copper conductor from external environmental factors, ensuring the long-term reliability and safety of the wire. In a construction setting where the wire may be exposed to different conditions, the PVC insulation is crucial for maintaining the integrity of the electrical connection.

(4) Different Sizes Available

• The availability of multiple cross-sectional sizes (1.5mm, 2.5mm, 4mm, 6mm, 10mm) allows for precise selection based on the specific electrical load requirements of the application. For example, smaller sizes like 1.5mm and 2.5mm may be suitable for lighting circuits or low-power appliances, while larger sizes such as 6mm and 10mm can handle higher current loads, making them ideal for power circuits or heavy-duty electrical equipment in construction projects. This versatility in sizing ensures that the wire can be used in a wide range of electrical installations within the construction site.

3. Technical Specifications

(1) Conductor Resistance

• The copper conductor has a specific resistance value per unit length, which is determined by the purity and physical properties of the copper. Lower resistance values are desirable as they result in less power loss during current conduction. The manufacturer typically provides detailed information on the conductor resistance to ensure that it meets the relevant industry standards and is suitable for the intended electrical applications.

(2) Insulation Thickness and Dielectric Strength

• The PVC insulation has a defined thickness to provide sufficient electrical insulation. The thickness is carefully calculated based on the rated voltage of the wire and the required safety margins. Additionally, the insulation has a certain dielectric strength, which indicates its ability to withstand electrical stress without breaking down. These technical parameters ensure the safety and reliability of the wire when used in different voltage levels within the construction environment.

(3) Current Carrying Capacity

• Each size of the wire has a specific current carrying capacity. This capacity is influenced by factors such as the conductor size, insulation material, and the ambient temperature in which the wire will operate. The manufacturer provides current rating tables or guidelines to help electricians and engineers select the appropriate wire size based on the expected current load. For example, a 2.5mm² BV wire may have a current carrying capacity of around 16 - 25 amps, depending on the specific conditions, while a 10mm² wire can handle significantly higher currents.

(4) Rated Voltage

• The wire is rated for a specific voltage range, which is usually indicated on the product packaging or in the technical documentation. Common rated voltages for construction wires may be 300V/500V or 450V/750V. The rated voltage determines the maximum voltage that the wire can safely handle without compromising its insulation and electrical performance. It is important to select a wire with a rated voltage that is appropriate for the electrical system in which it will be used.

4. Application Areas

• These single core BV/BVR PVC copper wires are widely used in various construction applications. They are commonly used in residential and commercial building wiring for electrical power distribution and lighting circuits. In a residential setting, they can be used to connect sockets, switches, and light fixtures. In commercial buildings, they are used for similar purposes as well as for powering office equipment, air conditioning units, and other electrical appliances. They are also used in industrial construction for wiring machinery, control panels, and other industrial electrical systems. Additionally, they can be used in outdoor construction projects where proper insulation and durability are required to withstand different weather conditions.

5. Installation and Maintenance

• Installation of the Construction Single Core BV/BVR PVC Copper Wire should be carried out by qualified electricians following the relevant electrical codes and safety standards. The wire should be properly routed and secured to avoid any mechanical stress or damage. When making connections, proper termination techniques should be used to ensure a reliable and low-resistance connection. For example, using appropriate wire connectors or soldering methods for joining the wires.
• Regular maintenance is recommended to check the integrity of the wire. This includes visual inspections for any signs of damage to the insulation, such as cracks, abrasions, or discoloration. If any damage is detected, the wire should be repaired or replaced immediately to prevent electrical hazards. Additionally, the electrical connections should be periodically checked for looseness or overheating. During maintenance, it is also important to ensure that the wire is not overloaded beyond its current carrying capacity to avoid premature failure and potential safety risks.

6. Quality Assurance

• The manufacturer of these wires adheres to strict quality control processes to ensure the consistency and reliability of the product. The copper used in the conductor is sourced from reliable suppliers and undergoes quality checks to ensure its purity and electrical properties meet the required standards. The PVC insulation material is also tested for its insulation performance, durability, and compliance with relevant safety regulations. Before the wires are released to the market, they undergo a series of quality tests, including electrical conductivity tests, insulation resistance tests, and mechanical strength tests. These tests help to ensure that each wire meets the specified technical specifications and provides reliable performance in construction applications. The manufacturer may also provide quality certifications and warranties to give customers confidence in the product's quality and durability.
