Stability Factor 314 days 0. The silane cross-linked polymer insulation also includes Icew inhibitors which provide resistance to UV degradation. LV aerial bundled cables. The results appear in Table 8. All of the premixed ingredients LLDPE, black masterbatch and silane were added to the mixer within 4 minutes.

It depends on the technical parameters and requirements of the cable.

Sample is free, but the freight. To test this hypothesis, samples of the second formulation KC when taken from the mixer were subsequently extruded into rods under the operating conditions described in Table 4. Results 3 products available Order by: Therefore, instead, small amounts of S-66-54 inhibitor were added during the milling procedure.

Diamond Member Since A second formulation KC was then developed as disclosed on Table 3 to determine if adding more silane would improve the cross-linking.

Professional teamwork service for e-66-524 actively. China laptop sample China free sample laptop China free sample oem. In one embodiment the invention is comprised of s–66-524 stranded electrical conductor core encircled by a conductor shield which is semi-conducting layer of tape or extruded plastic. Conductivity of KC, Sample E with 0. The black masterbatch is comprised of 1. What’s the MOQ of your cable?

  ASTM D1613 PDF

The LLDPE, silane and black masterbatch were allowed to mix for an additional 7 minutes for a total mixing time from start of 20 minutes.

To improve ingredient dispersion the overall mixing time was increased from 9 to 15 minutes. New standards are organized differently ICEA standards include s-66-542 for conductors, insulation, coverings, and construction details for wires and cables. The present invention uses a combination of linear low density polyethylene, carbon black and UV inhibitors as opposed to mineral fillers to meet the track resistant properties necessary for this application as airport lighting cables.

The polymeric material is doped with conductive carbon black and is cured with a peroxide curing agent. Resistance to abrasion, moisture and sunlight. 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.

After you pay the freight charge and send us confirmed files, the samples will be ready for delivery in The resulting temperature rise causes a drying out of the insulation.

Method for preparing organosilane-crosslinked-polyethylene insulation material for electric wire of 10 kV or below with double-step method. In power plants, industrial and operation installations, in residential areas and mining installations, in dry or wet locations. The mixture was then removed from the mixer and extruded into a number of rods under the conditions set forth in Table 6. However, hot creep testing was unsuccessful as the samples broke indicating that the mixture had not cross-linked.

Excellent properties against heat aging. Total mix time from the initial charge of ingredients into the mixer was 26 minutes.

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. We usually quote within 6 hours after we get your inquiry. This pressure was not present in the mixer. Many of our products have utility model patent certificate, which proves that our company has a strong ability to develop and innovate.


Send This is not what you are looking for? What is claimed is: That is, they lack an insulation shield.

ICEA Changes Cable Standard Strategy – January/February 2002

It’s all part of bringing the best wire and cable products to our customers. Another object of the invention is to provide a cost-effective, track resistant insulation by using low cost materials.

Total number of wires. This was followed by ifea 10 minute water and 1 minute air cool while maintaining high pressure.

Partially crosslinked ethylene vinyl acetate copolymers with low melt index values and increased tensile strength. A second batch of KC formulation was prepared so that enough icez was available to prepare a total of seven rods, identified by the letters A through G. After you pay the freight charge and send us confirmed files, the samples will be ready for delivery in days. A method of producing s-66-5224 track resistant, cross-linked insulation material for an electric cable comprising the steps of:.

This was attributed to the silane volatilizing in the mixer at the high temperatures and not to the low mixing pressure as originally thought. LV underground s-66-254 cables. US USB1 en These references, however, do not suggest the advantages of the present invention and they have different formulations, applications, or cross-linking methods.
