Custom-designed, top-loading oven

four independently hinged doors to expose the front and back of each loading station, steel plate oven floor and a workspace floor reinforced for 100lb loading on ¼" plate. Controls on the No. 984 include four special automatic door switches to shut off blower and heat when any door is opened, plus a digital programming temperature controller, manual reset excess temperature controller with separate contactors and recirculating blower airflow safety switch.

No. 984 is an electrically heated, 500ºF (260ºC) custom-designed top-loading oven from Grieve, currently used for curing connector assemblies onto long cables at the customer’s facility. Workspace dimensions measure 72" W x 8" D x 14" H. 12kW are installed in Nichrome wire elements to heat the unit, while a 600 CFM, ½ HP recirculating blower motor provides rear-to-front airflow across the workload. This top-loading oven features 4" thick insulated walls, aluminised steel exterior, type 430 stainless steel interior, Excellent conductivity through the use of diamond coated dies enable cable makers to cut costs. Bunching, stranding and compacting dies are often used to form multi-wire electrical cables. A bunching or stranding die groups single and multiple wires together, whereas a compacting die compacts the multi-wire strand to the required form factor. coating technology and tight diameter tolerances from Esteves diamond coated dies give the cable company the ability to save material and manufacturing costs. ultra-smooth chemical vapour deposited layer of diamond on a tungsten carbide die ensures the smoothest wire and cable surface. The diamond coated die is the combination of large-size availability of tungsten carbide and the surface properties of randomly oriented synthetic diamond. As electrical current flows through the surface of the wire a smooth surface State-of-the-art diamond The reasonably thick

leads to higher conductivity than was previously obtainable using tungsten carbide dies. This can enable the cable manufacturer to save raw material as the same conductivity is obtained with a smaller diameter cable. At the same time the diamond coated die reduces the amount of friction; reducing the amount of power that is required to bunch, strand or compact the conductor. ▲ ▲ A diamond coated die from the Esteves Group
