NTC Wind Energy developed and patented the first bolt caps in the wind industry over 20 years ago. In those days, lattice towers were just giving way to monopole towers and the industry was very small and tight. Since that time, the industry has grown exponentially and NTC Wind Energy has grown with it.
NTC Wind Energy prides itself in finding innovative solutions to common problems in design and construction of onshore wind turbine foundations. Rock anchor bolt caps, grout sleeves, specialty anti-corrosion grease and grease applicators are just some of the products that NTC Wind Energy provides. Low clearance, precision bolt tensioning and bolt restoration services are also provided.
Over the years, NTC Wind Energy has developed five generations of bolt caps, each one an improvement over the last. Most recently, NTC Wind Energy developed a heavy-walled injection molded polypropylene copolymer bolt cap that is UV resistant and stands up to almost anything nature can throw at it, the IronClad Super Duty bolt cap. This cap can be installed and removed by hand and features the only integrated o-ring in the industry.
One of the innovative solutions that NTC Wind Energy has developed is a water-proof air relief port built into the Super Duty bolt cap. This prevents a common issue with moisture being drawn into the cap as it expands from exposure to sunlight when water is pooled on the base flange. The IronClad Super Duty bolt cap is the only cap available with this important feature.
NTC Wind Energy provides utility scale wind turbine foundation solutions, products and services. Our patented Ironclad™ bolt caps are the premier bolt cap of the industry and are specified by nearly all foundation design engineers. In addition to cap installation and service, NTC Wind Energy provides IronClad grout sleeves, rock anchor bolt caps, foundation anchor bolt tensioning services, corrosion inhibiting grease, grease application tools and foundation anchor bolt restoration services.
NTC Wind Energy also specializes in solving unique problems associated with foundation construction. We’ve designed, fabricated and patented specialty tensioning tools to address problems associated with short bolts and tight tower wall clearances. We’ve also developed templates for bolt cage construction, cutting manpower by as much as 75% and greatly enhancing safety
