Earthquake Cable Protection


A Japanese market leading company has selected Vos Prodect articulated pipes in order to investigate whether the usage of systems can be preventive for the underground distribution and transmission lines against the damages of destructive earthquakes in Japan. For the onshore applications, it is common practice to use conventional cast iron pipes or conduits, which are found not to be providing sufficient protection, simply because of non rigid and non flexible construction.

Vos Prodect articulated pipes are well engineered products and mechanical tests of the systems have extensively been completed in order to provide a responsive and guiding information to the market.

Additional study will be conducted in Japan, on the behaviour of the unique application method of the systems. First trial will be realized to protect a repaired cable that was severely damaged by an earthquake. Due to split design of the systems, they can be easily assembled on the as laid cables.

Vos Prodect articulated pipes have a build-in bend restriction inside the strong joints, which provides flexibility during movements of the earth. Despite the fact that the movements are unpredictable, this study will broaden our minds to get better prepared to avoid future hazards. We are looking forward to sharing the results of this investigation.
