Wind power cable seals

UK based Roxtec targets power and wind-farm sectors with innovative new cable seal.

Roxtec has extended its range of cable seals with an innovative new seal specifically for underground power cables serving structures including electricity substations and wind turbines. The new Roxtec UG sealing system is ideal for power cables entering foundations or basements because it protects against flooding, humidity and continuous water pressure.

The UG seal is IP68-rated, 1 bar for catastrophic water pressure and 0.3 bar for constant water pressure. It can be used on trefoil single core cables. The system has been tested in Roxtec’s specialist test laboratory with retention tests of 1400N and 3300N depending on the product selected, meaning the system can handle the weight of many cables which is often the cause of failure in traditional sealants.

A knock-out sleeve is available and designed to be cast into the foundation structure. It is available in three different industry-standard sizes and designed to fit Roxtec seals and frames. A knock-out plate in the sleeve ensures a water-tight seal before cables are routed, meaning there is no water ingress during construction.

Conveyor belt cleaner

A new conveyor belt cleaner has been engineered to contain a smaller total volume of urethane, while maximizing the usable area, produced in a streamlined process that allows the manufacturer to reduce the purchase price and overall cost of ownership. Manufactured with Martin Engineering’s unique CARP (Constant Angle Radial Pressure) technology to maintain the most efficient cleaning angle throughout its service life, the Martin QB1 Cleaner HD features a no-tool replacement process that can be performed safely by one person in less than five minutes.

CARP technology is exclusive to Martin Engineering, designed to keep the blade at a consistent angle and pressure against the belt. Typically set at about 2 PSI (13.8 kPa) for the QB1 HD, the low blade-to-belt pressure helps protect the belt, splice and cleaner itself. As the blade wears, neither the surface area nor the angle is compromised, ensuring maximum performance throughout its life.

Diode technologies reduce solar inverter size

Cree Inc. (Nasdaq: CREE) has demonstrated that its best-in-class SiC MOSFET and diode technologies enable previously unattainable levels of power density in string solar inverter products, yielding efficiencies greater than 99.1 percent at peak at one-fifth the average size and weight of today’s silicon-based inverter units.

Using the latest Cree power MOSFETs and diodes, Cree’s systems engineering team designed a proof-of-concept 50kW string solar inverter that exhibits a remarkable 50 percent reduction in power loss and operates at three to five times the switching frequency that conventional silicon technology can currently achieve. The combination of these two factors drastically reduces both the size and weight of the inverter’s cooling system, as well as its filtering components, which translates into a unit-cost reduction approaching 15 percent.

Turbine linear actuator

The Voith SelCon was primarily designed as a linear actuator with safety function for the valve controls of gas and steam turbines.

The hydraulics provides high force density and dynamics, the electromechanical side contributes simple, cost-effective system integration. Large effective forces up to 500 kN and ATEX certification allow it to be used on turbines under virtually all conceivable ambient conditions.

The hydraulic system of the SelCon is self-contained. An external hydraulic power pack with oil tank, control block and pipework is completely unnecessary. This reduces procurement costs by up to 35 percent compared to a conventional solution. External hydraulic disturbances such as pressure fluctuations, mismatched pipe diameters or negative pressure in the tank line are out of the question.

The fail-safe function is implemented using an internal return spring. The trip time for the valve controls is typically less than 300 ms. This reduces the danger of direct and consequential damage considerably.
