A tie and support for cable bundles
This cable tie and support provides a safer and easier method for bundling and supporting cables outdoors. The Ty-Rap Deltec Cable Tie and Support System tolerates harsh environments and temperatures as low as -85°F. While traditional metallic lashings can nick or cut through cable insulation, the Ty-Rap system has no sharp edges. For aerial applications, the supports come with base hanger pieces. Cable straps are preassembled in standard lengths of 10, 13.5, and 27 in. Reels (pictured) are also available.

Adhesive works under water
This high viscosity methacrylate adhesive provides durable joints for assembling composites in a variety of environments, including immersion in salt water. SCIGRIP’s SG230 HV adheres to vertical or overhead surfaces without movement. The adhesive is two components with a 10:1 mix ratio. Functional with a number of activators, its working times range from 30 to 120 minutes. It is particularly suited for bonding large structural parts requiring long working times and for filling deep irregular gaps up to 1.5 inches (39 mm).
Rovings for non-crimped fabrics
SE 2020 Direct Rovings consist of continuous filaments bonded into a single strand and wound onto a bobbin. The single-end rovings are used to manufacture non-crimped fabrics for use in turbine blades. The boron-free E-CR glass offers improved corrosion resistance. Coupled with enhanced composite properties, it is well-matched for offshore wind farms. The fabrics are suitable for resin infusion or prepreg processes. The roving recently received GL approval.
Concrete repair at low temperatures
Repairing cracks in the foundation of a wind turbine will increase the life of the structure. Magna-Crete is a two-part magnesium phosphate material that sets rapidly and has high green strength. It bonds to concrete and other materials. Without a water additive, Magna-Crete may be applied at temperatures as low as -15°F. The company says work time may be 5 to 20 minutes while cure time may be 2 hours.
A torque multiplier with simple calculations
Each gear stage of a Norbar multiplier has a gear ratio of typically 5.45:1, which results in a true torque multiplication factor of 5:1. While the company says other multipliers often require graphs or formulae to calculate the input torque to achieve a particular output, Norbar requires simple multiplication. Norbar claims Handtorque has the most comprehensive multiplier range available. Standard products are available for hand torqueing up to 47,500 Nm (35,000 lbf·ft) and special orders to 100,000 Nm (73,000 lbf·ft).
Blue and green degreaser
Natural Blue is a concentrated biodegradable cleaner and degreaser for turbine blades, as well as a variety of metals and plastics. Diluted with water, the cleaner is suited for wipe down, pressure spraying, and immersion cleaning at room temperature or heated. Application temperature ranges from 60 to 120°F. It is non-flammable and non-toxic and contains no ozone-depleting chemicals. The liquid is CFIA approved.
Leveling system sports an iPhone interface
This level system consists of a sensor unit and an iOS unit, such as an iPad or iPhone. The ALiSENSOR Level is a rugged data collector that contains MEMS gyros, accelerometers, inclinometers, and a microprocessor. Data of angular and translational movements are provided via Bluetooth to the iOS unit, which has a user-friendly interface to analyze data. The system comes in two designs: The level core systems includes a 100-mm base and the Level VF includes an L-Shape base, a shaft and cylinder adapter, and two-spindle bit attachments.
Expansion bolts for shaft alignments
Turbines require fitted bolts to assure proper shaft alignment. Superbolt’s alternative, a six-piece expansion bolt, has a tapered stud with threads on both ends. The small-end Mechanical Tensioner supplies a large force to draw the tapered stud into an expandable tapered sleeve, creating a large radial load. The large-end Tensioner creates an additional high axial clamp load on the joint. Typically, sleeves are designed 0.005 to 0.010 in. loose in the hole, allowing for variations in tolerance. Other benefits include fast installation and removal and no need for high-powered tools.
Cable company adds 600V AWM rating
An industrial ethernet-cable manufacturer has added a 600V AWM approval. The rating for the DataMax Extreme line of cables has been applied to more than 25 part numbers and includes all FR TPE jacketed industrial ethernet cables. The more durable jacket required to meet a 600V approval protects the network from high voltage that may leach from nearby power cables onto data cables and travel into the communication network. Constructions are available in stranded, solid, unshielded, foil shielded, braided shield, 2 pair, 4 pair, 22, 24, and 26 AWG.
