Optical fiber protection 5 good
Different from the common cable, improve the OPGW life, the most fundamental is to improve fiber life, is mainly to improve the tensile strength, fiber static fatigue parameter and high temperature resistant performance.
5.1 high temperature resisting superior performance
Optical unit in protection of two layers of metal under a layer of aluminum clad steel wire - cable provides excellent mechanical properties, high purity aluminum - cable provides electrical and thermal properties to protect the best, all of these cable provides lightning resistance performance of the best.
- under the same conditions, extrusion aluminum tube OPGW cable shows more excellent performance, even at high intensity of lightning conditions, the light unit OPGW cable aluminum tube structure is not compromised, this is because the conductive and heat dissipation properties of aluminum is better than stainless steel; therefore, aluminum can be completely and quickly absorbed and the transfer of the arc current and energy, so as to reduce the damage, protect the light unit.

6 superior corrosion resistance
In OPGW optical cable technology used in extrusion molding aluminum structure cables, all metal surfaces are of the same kind of metal aluminum, so it will not produce electrolytic corrosion. Guarantee in mechanical, electrical performance index in the service life of OPGW.
- while in the stainless steel tube structure (according to the standard should not use insulating ointment), different metal (steel and aluminum) may come into contact with each other, thereby producing electrolytic corrosion. Stainless steel pipe and aluminum clad steel wire coated aluminum electrochemical potential difference, so easy to appear the phenomenon of electrochemical corrosion. Some steel structure suppliers by insulating ointment to prevent electrolytic corrosion is filled in between the steel tube and the armor wire. However, these ointment may be due to the high temperature produced by large current and fall, may also move due to vibration and temperature changes. So, using the ointment can not completely guarantee to avoid the occurrence of electrolytic corrosion, corrosion protection of steel structure is the best light unit uses the aluminum clad steel pipe.

-光单元管中，光纤松套绞合在非金属中心加强件上，填充纤膏以起阻水作用，并有足够的均匀余长。
-所有金属的接触面是相同的金属，从而可以完全避免不同金属之间接触可能产生的电化学腐蚀现象。
-光单元管内填充吸氢油膏。
-在光单元管的内壁的隔热保护带
-光单元管的壁厚、直径、短路电流热容量、抗拉强度，根据OPGW直径、额定拉断力、短路电流容量的用户限定，通过调节光单元铝管的壁厚与直径、选择导电率为20,3-27%IACS铝包钢外层单线，很容易实现外层全铝包钢、外层单线直径大的OPGW产品，而无须采用特别加厚铝层的铝包钢线，这样既提高了抗雷击性能，又不改变设计理念，比加厚铝层铝包钢外层单线机械性能更好，抗雷击性能更强。

3  高抗雷击性能
-根据OPGW直径、额定拉断力、短路电流容量的用户限定，通过调节光单元铝管的壁厚与直径、选择导电率为20.3-27%IACS铝包钢外层单线，很容易实现外层全铝包钢、外层单线直径大的OPGW产品，而无须采用特别加厚铝层的铝包钢线，这样既提高了抗雷击性能，又不改变设计理念，比加厚铝层铝包钢外层单线机械性能要好，抗雷击性能更强。
-PRYSMIANOPGW中的光纤，由于外层铝包钢线对热量的吸收和阻隔、厚壁铝管的散热、隔热包扎带和光纤松套管的隔热，当遭受雷击时，温升非常小，得到了很好的保护。
-PRYSMIANOPGW中的光单元，由于外层铝包钢线对热量的吸收和阻隔、厚壁铝管的散热,当遭受雷击时，温升较小，损伤概率很小。
-PRYSMIANOPGW的直流电阻略大于另一根地线，以降低OPGW被雷击概率。
-按IEC 60794-4-1-1999的试验标准，PRYSMIANOPGW通过试验证明铝管结构在中等水平的雷击条件下200库伦的电荷转移量，
-在OPGW成缆绞合过程中，通过科学计算和严格控制绞合工艺，即使外层断股，也不容易松散，从而避免造成电力系统短路的危害。

5  很好的光纤保护
     与普通光缆不同，提高OPGW寿命，最根本是要提高光纤的寿命，主要是提高光纤的抗拉强度、静态疲劳参数和耐高温性能。
5.1抗高温性能优越
-光单元处于两层金属的保护之下， 一层铝包钢线-为光缆提供极佳的机械性能，一层高纯铝-为光缆提供最好的电气、热学性能保护,所有这些为光缆提供最好的抗雷击性能。
-而相同条件下，挤压成型铝管结构的OPGW光缆表现出更加优异的性能，即使在高强度雷击条件下，铝管结构的OPGW光缆的光单元也不会受到损害，这是因为铝比不锈钢具有更好的导电、散热性能；所以，铝管能够完全、迅速地吸收、转移电弧电流和能量，从而降低损害，保护光单元。
-光纤的温升：

5.2抗疲劳参数好
-PRYSMIAN享有专利技术的吸氢油膏避免氢离子对光纤的损害。
-挤压制造的厚壁光单元管具有长期的气密性，防止潮气和水分的侵入。
-PRYSMIAN光缆的光纤的动态疲劳参数可达26以上。

5.3抗拉性能好
-光纤松套管制造过程中，冷缩形成的制造余长。
-层绞式光纤松套管，当OPGW被拉伸（或收缩）时，光纤从松套管中心位置向内（或向外）移动所能产生的长度变化。
-中心光纤，层绞式

6  优越的耐腐蚀性能
-在常用的OPGW光缆工艺中的挤压成型铝管结构的光缆组成中，所有金属接触面都是同一种金属-铝，所以不会产生电解腐蚀。保证在使用寿命内OPGW的机械、电气性能指标。
-而在不锈钢管结构中（按照标准不应使用绝缘油膏），不同的金属（钢和铝）可能相互接触，从而产生电解腐蚀。不锈钢管与铝包钢线的包铝存在电化学电位差，所以容易出现电化学腐蚀的现象。一些钢管结构的供应商通过在钢管和铠丝之间填充绝缘油膏来避免电解腐蚀。但是，这些油膏可能由于大电流产生的高温而滴落，也可能由于振动和温度的变化而移动。所以，使用油膏并不能完全保证避免电解腐蚀的发生，钢管结构最好的防腐保护是使用铝包钢管的光单元。

7 型式试验优越的各特性
-PRYSMIAN有自己的试验室，能完成除短路试验外几乎所有的OPGW型式试验，包括雷击试验。因此，我们能提供各种缆型完整的型式试验报告。
