Are you troubled by the need to inspect bare conductors every two years? Are you troubled by the short life of conductors in coastal areas? Are you worried about conductor breakage caused by breeze vibration? The use of Preformed Armor Rods can solve your problems.
Preformed Armor Rods are used to protect conductors from vibration, clamp pressure stress, friction, arcing and external damage. Preformed Armor Rods adopt a streamlined design, which can effectively reduce the vibration of wind on the line. Preformed Armor Rods reduce material and installation costs while providing excellent performance, and have a higher cost-effectiveness than traditional line protection. Preformed Armor Rods have a compact appearance and a modular design, which can support rapid replacement and maintenance, reducing the maintenance costs required by the company in the later stage.
The Baihetan-Jiangsu UHV project encountered a once-in-50-year ice disaster. Continuous freezing rain caused the line ice thickness to reach 45mm, and the local wind speed was 28m/s. The high-strength Preformed Armor Rods used in this section successfully ensured the safety of the conductors, and the accident rate was reduced by 92% compared with the traditional sheath section. However, a 330kV line did not use protective wires. After 7 years of operation, it was found that the outer aluminum strands of the conductor were 100% broken. The steel core alone was used for support, and the repair cost reached 4 million yuan/km. It can be seen that Preformed Line Protector are not "optional" but "must-have". In the construction of modern power grids, protective wires have become core components as important as conductors.
Choosing Preformed Line Protector can reduce frequent maintenance. The addition of pre-twisted protective wires can extend the maintenance cycle of conductors from 2 years to more than 8 years, reducing 80% of the maintenance workload. Preformed Line Protector' special coating technology can resist salt spray corrosion, and the life of conductors in coastal areas has been increased from 15 years to 30 years, saving the cost of repeated replacement. The spiral damping design of Preformed Line Protector can effectively absorb vibration energy, reduce the wear rate of conductors, and solve the problem of conductor breakage caused by breeze vibration.
The Preformed Line Protector produced by our company have received unanimous praise. Our company has always regarded the safety of distribution and transmission line products as the lifeline of the enterprise, and developed high-quality products to meet customer needs.
