EXPANSION OF OUR SUBSEA CABLE FACILITY IN NORWAY

Norway Optical Cable Splicing Project

The project involves the construction of a new high-capacity fibre optic cable stretching from Trondheim to Alta. Subsea infrastructure is considered a vulnerable target in a hybrid threat landscape. Our fitters work daily with branching and splicing of fiber in pull troughs, splice cabinets, masts, etc. The cable, which will be produced at Nexans' plant in Rognan, is designed to provide a secure and reliable subsea fibre connection. IOEMA-1 is a state-of-the-art, high-capacity, 1400 km repeatered submarine fibre optic project that will arc across five key northern European markets – the UK, The Netherlands, Germany, Denmark and Norway. Nexans Norway AS accomplished significant achievements in December 2025 with the hull launch of Nexans Electra at Ulstein Verft and Space Norway awarding them with a contract for Bodo-Fauske link fibre-optic cable installation work.

How long should cable trays be fitted with expansion joints

For a 100° F differential (winter to summer), a steel cable tray will require an expansion joint every 128 feet and an aluminum cable tray every 65 feet. Cable tray systems, essential for supporting electrical cables, are subject to thermal expansion and contraction due to temperature fluctuations. In case there is no space to move it, the tray could become deformed or break the bolts that attach. The mechanical and electrical characteristics, tests, certifications, overall quality management, recommendations mentioned in this technical guide only apply to our own cable management ranges and cannot under any circumstances be transposed to si osure, overheating or.

Do cable tray expansion joints need a grounding wire

If an EGC cable is installed in or on a cable tray, it should be bonded to each or alternate cable tray sections via grounding clamps (this is not required by the NEC® but it is a desirable practice). The intent of this article is to review grounding practices for cable tray wiring systems. This article provides a comprehensive framework that governs various aspects of cable tray installations, including the types of cables that are deemed acceptable for use, requirements for grounding and bonding, and stipulations regarding tray fill capacity. This provides a safe path for any stray electrical currents to flow safely into the earth, avoiding damage to your equipment and reducing the risk of electric shocks.

What are the problems with cable tray expansion and contraction

If not properly accommodated, the accumulated length change can: Buckle or deform the tray system in summer (expansion). The cable trays made of metal, in fact, expand and contract depending on the temperature. 1993 NEC Section 300-7 (b) states that "Raceways shall be provided with expansion joints.

Construction cost of mesh cable trays

Basic cable tray systems cost $3-15 per foot depending on type and material Installation labor adds $5-8 per foot to total project costs Ladder trays typically cost 20-30% less than solid bottom systems Bulk orders of 1000+ feet can reduce unit pricing by 15-25% Regional variations. Cable trays will tend to be significantly less expensive to use in 2026 than metal pipes due to their faster installation. Wire mesh trays often come out ahead on total installed cost because: Labour time is lower. The main cost driver is the material used in manufacturing: 🔹 Galvanized steel is the most common.
