The sheath of the twist-resistant, cold-resistant, flame-retardant Flexible Cable for wind power generation developed by the Far East has flame retardant, oil resistance, cold resistance, and high mechanical and physical properties. In the past, CPE was generally used as the rubber skeleton material. However, when pure CPE is used as the main material, the finished cable sheathing rubber with CPE skeleton cannot meet the requirements of low temperature stretching at -40°C; when CPE/EPDM is used in common, the finished product Sheathing rubber can reach the requirements of low temperature stretching at -40°C, but its oil resistance performance can not meet the standard requirements; When using CPE/EPDM/NBR ternary sharing, the finished sheath rubber can reach -40°C low temperature stretching. Requirements, oil resistance can also meet the standard requirements, but the flame-retardant performance has dropped; Far East developed wind-resistant cable with a cold-resistant jacket rubber in the CPE/EPDM/NBR based on the common use of new composite flame retardant to improve The flame-retardant properties of the system and the materials used at the same time are all environmentally-friendly, which avoids damage to the local ecological environment. At present, cold-resistant environmental protective jacket rubber for wind power soft cables has been mass-produced in Far East Cable Co., Ltd.
Bare aluminium conductors are electrical conductors made from pure aluminium. They are used in various electrical applications, including overhead power transmission and distribution lines.
Bare aluminium conductors have several advantages over other types of conductors. Firstly, aluminium is lighter than copper, which makes it easier to handle and install. This is particularly important for overhead power lines, where the weight of the conductor can have a significant impact on the cost and feasibility of the project.
Secondly, aluminium has a higher conductivity-to-weight ratio than copper. This means that for a given weight, aluminium conductors can carry more current than copper conductors. This makes them more efficient in terms of power transmission.
However, bare aluminium conductors also have some disadvantages. One major drawback is their lower mechanical strength compared to copper conductors. This makes them more susceptible to sagging and stretching under the weight of their own span, especially in hot weather conditions. To address this issue, aluminium conductors are often reinforced with steel strands to improve their mechanical strength.
Another disadvantage is that aluminium has a higher resistance than copper, which can result in higher power losses and voltage drops. To mitigate this, aluminium conductors are typically designed with larger cross-sectional areas compared to copper conductors to compensate for the higher resistance.
Overall, bare aluminium conductors are widely used in electrical power transmission and distribution systems due to their cost-effectiveness, lightweight, and high conductivity-to-weight ratio. However, careful design and installation considerations are necessary to ensure their mechanical strength and minimize power losses.
