Strongwell设计了一种玻璃纤维电杆,可直接替代现有的木杆,钢杆和混凝土杆。
 
电气用途材料通常使用木材,钢或混凝土制造。这是因为它们天生的多功能性,以及它们已被建立为建筑材料数十年的事实。有史以来建造的第一个电力杆是由木材制成的,这得益于优异的强度 - 重量比和良好的延展性,以抵抗与风相关的损坏。电网和广泛的输电线路系统现在在世界范围内普遍存在,在这些基础设施系统中发现了木材,钢和混凝土电线杆的组合。然而,这些已建立的工业材料今天表现出与首次建立电气传输设置时相同的机械缺陷。
 
木材本质上是吸湿的并且易于腐烂,而钢产品在大气条件下迅速氧化和腐蚀。污染物和风化会降低木材,钢材和混凝土电线杆的机械稳定性,导致部件过早失效和显着的安全风险。
 
玻璃纤维电线杆为传统材料的问题提供全面的解决方案。本文将探讨玻璃纤维电线杆的特性以及它们如何提高基础设施的安全性:玻璃纤维电线杆的容量。
 
Strongwell设计了一种专有的玻璃纤维电杆,可直接替代现有的木杆,钢杆和混凝土杆。这种轻质产品由拉挤成型构件构成,在木材和钢材上提供低导电性和改进的强度重量比。它比木材轻约30%,比钢轻60%。这种机械稳定性和轻盈性的结合由高性能成分矩阵提供,从内部多向玻璃纤维织物到高强度树脂饱和度。
 
这种施工方法的直接好处是否定腐烂或生锈。这极大地提高了传动阵列的耐用性,并降低了由于机械故障引起的事故风险。由于其出色的抗冲击性,电线杆进一步受益于玻璃纤维的材料结构。它采用内部泡沫芯设计,用于冲击吸附,以减少意外交通碰撞中驾驶员的危险。在一些车辆与玻璃纤维电线杆相撞的事故中,撞击很大程度上被材料的结构所吸收,从而避免了严重的伤害。
 
由于其轻质特性和低导电性,玻璃纤维还具有安装和维护安全性的优点。玻璃纤维电线杆可以在不降低工作压力或受伤风险的情况下竖立,对使用该材料几乎没有特别的考虑。由于它具有低导电性,因此可以与木质电线杆类似地接地,从而降低了与不熟悉材料相关的风险。它也可以钻孔,以便于安装关键的传输导体和变压器。

Fiberglass power poles for safer infrastructures

Electrical utility materials are regularly fabricated using wood, steel, or concrete. This is due to their innate versatility, and the fact that they have been established as building materials for decades. The first power poles ever erected were fabricated from wood, benefiting from excellent strength-to-weight ratios and good levels of ductility to resist wind-related damage. Electrical grids and extensive transmission line systems are now commonplace worldwide, with combinations of wood, steel, and concrete power poles found within these infrastructural systems. Yet these established industry materials exhibit the same mechanical drawbacks today as they did when electrical transmission setups were first established.

Wood is hygroscopic in nature and prone to rotting, while steel products rapidly oxidize and corrode in atmospheric conditions. Pollutants and weathering can degrade the mechanical stability of wood, steel, and concrete power poles, resulting in premature component failure and significant safety risks.

Fiberglass power poles provide comprehensive solutions to the problems of conventional materials. This article will explore the properties of fiberglass power poles and how they can improve infrastructural safety: capacities of fiberglass power poles.

Strongwell has designed a proprietary fiberglass power pole to directly replac existing wood, steel, and concrete poles. This lightweight product is constructed from pultruded components, providing low-conductivity and an improved strength-to-weight ratio over both wood and steel. It is roughly 30% lighter than wood and as much as 60% lighter than steel. This combination of mechanical stability and lightness is provided by a matrix of high-performance constituents, from an interior, multi-directional fiberglass fabric to a high-strength resin saturation.

The immediate benefit of this construction methodology is the negation of decay or rust. This radically improves the durability of the transmission array and reduces the risk of accidents due to mechanical failure. Power poles benefit further from the material structure of fiberglass due to its outstanding impact resistance. It features an internal foam core designed for impact adsorption, to reduce the danger to drivers in accidental traffic collisions. In several incidents wher vehicles have collided with fiberglass power poles, the impact was largely absorbed by the material’s structure, thus avoiding serious injury.

Fiberglass also offers benefits for installation and maintenance safety due to its lightweight nature and low-conductivity. Fiberglass power poles can be erected with reduced risk of strain or injury for workers with few special considerations for using the material. As it is low-conductive, it can be grounded similarly to wood power poles, reducing risks relating to unfamiliarity with the material. It can also be drilled for easy installation of critical transmission conductors and transformers.
