om;d.c;dar;tan;s-s;avi;w/d;cho;jzaUsing the Entry Heat Treatment EHT method, heavy wall cores for HV and EHV cables can be manufactured in CCV lines with excellent roundness and concentricity with high repeatability. Sensitive Milliken type and taped conductors can be insulated with only moderate rotating without a risk of damaging the conductor. The method also extends the usability of standard cheaper insulation material with higher wall thicknesses.
Entry Heat Treatment EHT is applied when running high and extra high voltage cables in a catenary or a vertical CDCC line. In the EHT, the melt and the cross-linking of the insulation are under controlled heat treatment.
In the EHT the inner layer of plastics forms a solid layer around the conductor, creating a bigger supporting area for the outer plastics material and preventing it from drooping.
The outer layer of the insulation is cooled down at the beginning of the catenary section, and thus the cable geometry remains round as it is extruded.
After the EHT section, the curing process works so that the outer layers, while being cured, are supported by the solid inner layers. After this the round form is supported by the cross-linked outer layer.
Nitrogen circulation unit
The EHT circulation unit consists of a gas circulation blower, a heat exchanger, 3 pieces of by-product outlets and all necessary valves and instruments. All these components have been installed on the same frame, which forms one complete unit.
The EHT circulation unit is ready-fitted and completely tested.

The 100th multi-layer PAL line is going to Chinaust and in particular to their facilities in Changchun in northeast China. Factory Acceptance Tests took place during the last days of June 2019 in the presence of a four person delegation led by Li Hongjie, General Manager of Changchun Chinaust. Not only was it the occasion to mark a successful acceptance by the customer, but also to highlight the delivery of the 100th multi-layer automotive tube extrusion line. Indeed, representatives from both companies began plans for celebrating Chinese style once the line ready for production. Read more

Maillefer has recently acquired a Cable Checker unit for our new R&D lab. The unit is essentially a microscope connected to a hot oil bath for high resolution analysis of all parts of the cable. This equipment is particularly suited for inspection of extruded XLPE (cross-linkable polyethylene) insulated Medium, High and/or Extra-High Voltage cable samples. Both trouble shooting and quality control inspection are done with very high accuracy. Read more
