Cyclone Phailin, which battered the Odisha coast, has left the power distribution infrastructure in a shambles, said National Disaster Management Authority vice-chairman Marri Sasidhar Reddy, anticipating that it would be 15 days before normal service could be resumed in the area.
He is urging governments to install underground power cables in coastal areas to minimise the damage. Such projects can be taken up under the World Bank-funded National Cyclone Risk Mitigation project.
Nexans’ newest product, Energex® Extra, uses Dow Endurance™ HFDC-4202 tree-retardant cross-linked polyethylene (TR-XLPE) insulation.
The advantages of Energex Extra using Dow Endurance HFDC-4202 are said to include improved resistance to water tree growth, higher retained dielectric strength after ICEA 360-day accelerated water treeing test (AWTT) and reduced cost of ownership through longer cable life.
Ridgway Machines has launched a new MTM Mobile Coil Taping Machine with a unique mobile carriage mounted taping head. The carriage seats the operator and travels along the machine length to simplify the application of insulation tapes to larger size electrical coils or bars, whilst ensuring that the highest levels of quality and productivity are achieved.
The MTM is specifically designed for handling larger size coils and bars, up to 4,000mm straight length, using a combination of retractable pneumatic coil supports, adjustable rear clamp stands and coil eye supports.
The robust taping head travels in both directions – as the carriage approaches the coil supports, the clamps open automatically and the support arm moves away to the rear of the machine.
Downtime is eliminated as the machine can be operated continuously in both directions to apply multiple tape layers. The taping head rotates around the coil, applying a pair of tapes simultaneously with tension being settable between 0.5 and 7kg direct pull. Feeding angle is automatic as the correct angle is always found either side of the centre line.
The MTM uses twin variable speed motors to provide and synchronise the taping head drive and carriage traverse functions. These are controlled by a foot pedal mounted on the taping head carriage, with reversing selection by joystick control located on the panel in front of the operator. Additional controls provide safety guard/bump strip reset, and factory pre-set acceleration and deceleration ramps ensure gentle start and stop operations.
