Tree Wire Cable 15 Kv 3-Layer AAC (ANSI/ICEA S-66-524)
ss-66-524 Once receive your question, the supplier will answer you as soon as possible. Electrical insulating tape prepared from an ethylene-propylene copolymer composition. The insulation material meets Federal Aviation Administration technical requirements for airport lighting applications.
China Tree Wire Cable 15 Kv 3-Layer AAC (ANSI/ICEA S) – China ABC Cable, XLPE Cable
Year of fee payment: The key difference in the new ICEA standards is the way they are organized. Additionally, the milling and molding procedure was slightly changed. Strong technical support technical data, drawing, etc. The conductor shield would preferably be peroxide cross-linked if it is extruded or more preferably silane cross-linked.
The results demonstrated full compliance to the physical, electrical, aging lcea non-tracking properties needed for applications as underground electrical cable for airport lighting circuits. ICEA standards include requirements for s-66-254, insulation, coverings, and construction details for wires and cables. After price confirmation, you can require for samples to check our quality. Conductivity of KC, Sample E with 0. What’s the MOQ of your cable?
What is claimed is: Send link to this page. These references, however, do not suggest the advantages of the present invention and they have different formulations, applications, or cross-linking methods. S-66-5524 Factor 314 days 0. The cross-linked insulation material of claim 1 or claim 2wherein said carbon black comprises about 0.

Therefore, instead, small amounts of UV inhibitor were added during the milling procedure. That is, the antioxidant, carbon black, metal ices and UV inhibitor are not integral parts of the cross-link structure. Application Power distribution in medium voltage. Method for preparing organosilane-crosslinked-polyethylene insulation material for electric wire of 10 kV or below with double-step method.
Both surrounding layers may comprise polymeric material such as polyethylene which is doped with carbon black of specific grades and in particular concentrations. The cross-linked insulation material of claim 1 or claim 2wherein said linear low density polyethylene base resin has a melt index of about 0.
This discharge can track along the surface of the cable leading to premature cable failure. Once the rod material was melted on the mill, UV inhibitors in powder form were added in the amounts set forth on Table 7. A 10 minute water followed by ice 1 minute air cool followed while maintaining high pressure. Unaged Physical Properties Tensile Strength, psi min. Send your message to this supplier. New standards are organized differently ICEA standards include requirements for conductors, insulation, coverings, and construction details for wires and cables.
What is the warranty for the product? This was followed by a 10 minute water and 1 minute air cool while maintaining high pressure. Additionally, the present invention uses commodity resins and cross-linking via silane to significantly reduce the raw material costs.
How long can I expect to get the sample? Description Characteristics Products and services Docs and info Description Power distribution in medium voltage. Add to favorites Compare Apply. Cable insulation system with flexibility, high temperature deformation resistance, and reduced degree of stickiness.
But if there’s any exceptional situation, we can make some negotiations. This pressure was not present in the mixer. MV substation power cables.
NA2XC2Y 15 kV NC33; ICEA S-66-524; ICEA S-94-649
The speed of the mixer blades was initially set at 10 RPM and the total batch size was grams. To improve the unaged icra weathered physical properties, including the UV resistance, the KC formulation shown on Table 3 was modified. Once this happens the dry surface area so formed can frequently encounter electrical stress greater than the insulation air interface, thereby resulting in a spark or scintillation.
Unaged elongation was acceptable; however, the unaged tensile strength was considered marginal and the weathering results for retained elongation showed failure. Similarities between Penfold and the present invention are that both employ silane crosslinking.
A track resistant, non-shielded, electric power cable comprising:. After about 5 minutes of mix time, about 4 grams of the silane was added to the chamber.
Zone 1 Zone 2 Zone 3 Screen Pack: 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. Another object of the invention is to provide a cost-effective, track resistant insulation by using low cost materials. S6-6-524 last three components extruded CV continuous vulcanization triple extrusion.
