How to handle cable trays in utility tunnels via expansion joints
The cable tray needs to be anchored at the support closest to the midpoint between the expansion joints with hold down clamps and secured by expansion guides at all other support locations. The expansion guides allow the cable tray to slide back and forth as it. Cable tray systems, essential for supporting electrical cables, are subject to thermal expansion and contraction due to temperature fluctuations. As cables and trays expand or contract, they can cause stress on the structure, leading to potential damage or misalignment. This subject. ass reinforced polyester) cable trays. These solutions provide optimum safety, flexibility and excellent corrosion resistance for ety lighting, signs, ventilation, etc.

High-speed DAC cable for metropolitan area networks SFP
DAC cables are high-speed, copper-based cables designed for connecting networking devices over short distances, especially in data centers. These cables come pre-terminated with SFP (Small Form-factor Pluggable) or QSFP (Quad Small Form-factor Pluggable) connectors which simplify. An SFP+ Direct Attach Copper (DAC) is a twinax copper cable with SFP+ connectors permanently attached at both ends. The Amphenol SFP-DD products offer an ultra-high-performance, cost-effective solution for 100G aggregate speed applications in switches, routers, data storage arrays, and high-performance computer (HPC) clusters. The port cannot be replaced, and the module head and copper cable cannot be separated. Applications include: InfiniBand.

Papua New Guinea Bridge Construction
Prime Minister James Marape on 9 March 2026 officially opened 35 newly constructed permanent bridges along the Highlands Highway, describing the country's most important transport corridor as the backbone of Papua New Guinea's economy. One of Papua New Guinea's modern climate-resistant bridges. The Bougainville Island is a volcanic island and about half of the land area is hilly or mountainous, with peaks rising to 1500 to 2400metres. The. Works and Highways Secretary David Wereh has praised the completed nine new climate-resilient bridges—three in East Sepik and six in Madang— as transformative impact project as it will boost the livelihoods of over 40,000 people in the rural areas along the Sepik and Ramu Highways. "It has brought. The Project will improve Papua New Guinea's (PNG) two-lane national road network by replacing narrow temporary modular steel (or Bailey) and other deteriorated bridges with permanent two-lane structures. The reusable Bailey bridges will be reassembled on rural roads to improve access.
