I. Introduction to 10kV Overhead Insulated Conductors
10kV overhead insulated conductors are widely used in power transmission lines. They offer excellent electrical performance and high mechanical strength. They are not only resistant to harsh weather conditions but also effectively reduce line losses, improving grid efficiency. A variety of models are available, tailored to different application scenarios and requirements.
II. Common 10kV Overhead Insulated Conductor Models and Parameters
1. JKLYJ-10KV-1×95 Model
This is a single-core copper conductor overhead insulated conductor with a rated voltage of 10kV. The conductor has a nominal cross-section of 95 mm² and is a compressed round copper conductor. The insulation is made of cross-linked polyethylene (XLPE), which offers excellent electrical performance and heat resistance. This conductor is commonly used in urban and rural power transmission and distribution systems.
The main parameters are as follows:
* Rated voltage: 10kV
* Conductor material: Copper
* Nominal conductor cross-section: 95mm²
* Insulation material: Cross-linked polyethylene (XLPE)
* Maximum operating temperature: 90°C
2. JKLYJ-10KV-1×120 Model
This conductor is similar to the previous model, but the conductor's nominal cross-section is increased to 120 square millimeters. It is suitable for applications requiring higher current transmission capacity.
The main parameters include:
* Rated voltage: 10kV
* Conductor material: Copper
* Nominal conductor cross-section: 120mm²
* Insulation material: Cross-linked polyethylene (XLPE)
* Maximum operating temperature: 90°C
1. Conductor Cross-sectional Area
The conductor's cross-sectional area is a key factor affecting its current-carrying capacity. Generally speaking, a larger cross-sectional area means a higher current-carrying capacity, but this also translates to higher costs and greater installation difficulty. Therefore, when selecting wire, we need to balance the cross-sectional area with the actual load requirements and budget.
2. Rated Current
The rated current refers to the maximum current allowed to flow through a wire under normal operating conditions. This value is generally related to the wire's cross-sectional area and material properties. When selecting wire, we need to ensure that the wire's rated current can meet the system's maximum load requirements to avoid safety accidents caused by overload.
3. Resistance
Resistance reflects the degree to which a wire impedes current flow. Generally speaking, lower resistance indicates better conductivity and lower energy loss. Therefore, when selecting wire, we should strive to choose products with lower resistance to improve system transmission efficiency.
4. Insulation Thickness
Insulation thickness is a key factor affecting wire insulation performance. Thicker insulation provides better electrical isolation, but it may also increase the weight and cost of the wire. When selecting wire, we need to determine the appropriate insulation thickness based on the actual use environment and technical requirements.
5. Tensile Strength
Tensile strength reflects the wire's ability to resist external forces. In outdoor overhead lines, conductors must withstand the elements, including wind, rain, and snow. Therefore, high tensile strength is crucial. When selecting conductors, we should pay attention to their tensile strength to ensure they can maintain stable operation in harsh environments.
III. Choosing the Right 10kV Overhead Insulated Conductor Model
When selecting a 10kV overhead insulated conductor model, factors such as transmission capacity, operating environment, and cost budget should be considered. For applications requiring higher transmission capacity, a model with a larger conductor cross-section can be selected. For harsh environments, conductors with higher weather and corrosion resistance are required. Cost is also an important factor when selecting a conductor model.
