This was attributed to the silane volatilizing in the mixer at the high temperatures and not to the low mixing pressure as originally thought.

That is, the antioxidant, carbon black, metal deactivator and UV inhibitor are not integral parts of the cross-link structure. You Might Also Like.

How do you ship the products? A plaque sample was tested and yielded excellent physical test results.

The black masterbatch is comprised of 1. Cable insulations made according to this invention are stated to have enhanced tree resistance, heat resistance, abrasion resistance, flexibility and cure under ambient conditions.

After price confirmation, you can require for samples to check our quality. The results appear in Table Both surrounding layers may comprise polymeric material such as polyethylene which is doped with carbon black of specific grades and in particular concentrations.

Antioxidants can be used in an amount of about 0. A 10 minute water cool and then a 1 minute air cool followed while maintaining high pressure. It depends on the technical parameters and requirements of the cable.

NA2XC2Y 15 kV NC33; ICEA S; ICEA S – Nexans

Now ICEA is replacing those familiar standards, along with electric utility standards that have also been used for many medium voltage industrial applications. No UV inhibitors were added. A second formulation KC was then developed as disclosed on Table 3 to determine if adding more silane would improve the cross-linking. The MOQ of our most cable is meters. S-666-524 voltage was 13 kV AC for 5 minutes. However, Penfold uses homogeneously branched, substantially linear ethylene polymers as contrasted with the linear low density polyethylene of the present invention which is a conventional heterogeneously branched polyolefin resin prepared with a coordination catalyst.


Tree Wire Cable 11 Kv 3layer ACSR ANSI/Icea S-66-524

However, cross-links can terminate on the antioxidant, carbon black, metal deactivator and UV inhibitor to a small degree and therefore these ingredients of the insulation material of s-66-524 present invention can be part of the cross-link structure. ICEA standards include requirements for conductors, insulation, coverings, and construction details for wires and cables.

The silane weight percentage was increased from 1. Stock available, Free sample is available.

ICEA S-66-524 –S-68-516

The samples broke and failed immediately. People who viewed this also viewed. MV substation power cables.

This was again followed by a 10 minute water and 1 minute air cool while maintaining high pressure. Sample is free, but the freight. US USB1 en The overall mixing time was maintained at 15 minutes and the torque was increased over previous mixing procedures from mg to mg. And the quote will be sent to you in days. It was thought that perhaps the pressure about psi present during the extrusion process was responsible for getting the silane to graft in the extruder.

The RPM of the mixer blades was adjusted to ensure that the torque stayed below 10, mg as the temperature increased and the mixture d-66-524. Zone 1 Zone 2 Zone 3 Screen Pack: Although preferred embodiments of the present invention have been described and illustrated, it will be understood s-66524 those skilled in the art that various modifications may be made without departing from the principles of the invention. Unaged elongation was acceptable; however, the unaged tensile strength was considered marginal and the weathering results for retained elongation showed failure.

How can I get a sample to check your quality? The single FIGURE of the drawing illustrates a ices conductor, electric power cable 1 having a central conductor 2 with a conductor shield 3 and an insulation layer 4 extending therearound.

In order to achieve the required performance, a balance between UV protection and insulative properties, that is, dielectric strength is needed. You will get a sample for free if we have the storage of that cable.


Z-66-524 creep and physical properties of these samples were tested. The present invention uses a combination of linear low density polyethylene, carbon black s-66-24 UV inhibitors as opposed to mineral fillers to meet the track resistant properties necessary for this application as airport lighting cables.

Because the tracking resistance of this formulation had proven to be acceptable, it was decided that increasing the carbon black level could detrimentally alter this property. Unaged Physical Properties Tensile Strength, psi min. Exterior armoring or shielding layers may also be present where required.

It is one of key enterprises of China wire and cable industry, the national high-tech enterprises, the innovation and development pilot enterprises of Jiangsu Province, the private technology enterprises in Jiangsu Province, keeping Contract and Credit Enterprises and AAA-grade credit enterprise. See the complete description. What about the lead time for mass production? The new ICEA standards also reflect the latest cable construction technologies, including improvements in the ability to manufacture “round” cables.

China sample surface China camera free samples China free sample will. As previously described, the UV inhibitor in powder form was added to the melted material on the mill. If you continue your browsing, we assume that you accept our use of cookies. The mixture at this point was still unmelted. Rather than premixing the ingredients of KC together, the mixer was charged with the LLDPE, then the silane, and then the black masterbatch as disclosed below.

The cross-linked insulation material of claim 1 or claim 2wherein said carbon black comprises about 0. The need for track-resistant properties in such applications stems from the fact that because such cables lack iccea insulation shield, the cable can be prone to surface discharge.

UV stabilisation of a cross-linkable polyolefin composition comprising an acidic silanol condensation catalyst.
