Add to favorites Compare Apply. Many industrial cable specification writers also refer to AEIC cable specifications for the qualification testing those standards require.

In power plants, industrial and operation installations, in residential areas and mining installations, in dry or wet locations. Initial attempts to provide an insulation material having the properties necessary to comply with ICEA S and FAA L specifications began with the formulation disclosed in Table 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.

Now ICEA is replacing those familiar standards, along with electric utility standards that have also been used for many medium voltage industrial applications. This was attributed to the silane volatilizing in the mixer at the high temperatures and not to the low mixing pressure as originally thought.

Generally speaking, this phenomenon results when the non-shielded insulation gradually acquires a conductive film on its surface from contamination, moisture, or polymer degradation which, when the insulation is subjected to a voltage stress, will over time allow a small amount of leakage current to be discharged and conduct along the surface of the insulation.

The results appear in Table 5: Electrical insulating tape prepared from an ethylene-propylene copolymer composition. Results 3 products available Order by: Stock available, Free sample is available. Because the tracking resistance of this formulation had proven to be acceptable, it was decided that x-66-524 the carbon black level could detrimentally alter this property.


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. Total number of wires. Can I get samples before placing the order? The method of claim 13wherein said black masterbatch includes a metal icez. That is, the antioxidant, carbon black, metal s6-6-524 and UV inhibitor are not integral parts of the cross-link structure.

Description Power distribution in medium voltage. It’s all part of bringing the best wire and cable products to our customers. The conductor shield would preferably be peroxide cross-linked if it is extruded or more preferably silane cross-linked. The single FIGURE of the drawing illustrates a single conductor, electric power cable 1 s-6-524 a central conductor 2 with a conductor shield 3 and an insulation layer 4 extending therearound.

The hot creep data indicated that the KC formulation had cross-linked. Electrically conductive compositions comprising an ethylene polymer, a mineral filler and an oiled, electrically conductive carbon black.

How can I get a sample to check your quality? The RPM of the mixer was raised to 20 as soon as the torque would allow. Continue Find out more on how we use cookies. The samples broke and failed immediately.

Send link to this page. 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. SIC, 1 day 2. Field of the Invention The present invention relates to improved insulation for electrical power cables which has both weathering and track resistant properties. The principle use for this insulation is with 5 kV and low voltage non-shielded electrical power cables in airport lighting applications.

It was thought that perhaps the pressure about psi present during the extrusion process was responsible for getting the silane to s-66–524 in the extruder. The results appear in Table 8. S-6-524 the samples failed. Honestly, it depends on the order quantity and the season you place the order.


Main content Main menu. Many of our products have utility model patent certificate, which proves that our company has a strong ability to develop and innovate.

The mixture was then removed from the mixer and extruded into a number of rods under the conditions set forth in Table 6. Based on prior laboratory tests where the initial formulation KC had been successfully cross-linked when extruded onto copper wire, it was not understood why molded plaques made directly from the Brabender mix did not cure. The conductor 2 may be stranded as shown or may be a solid conductor. This was again followed by a 10 minute water and 1 minute air cool while maintaining high pressure.

On a macroscopic level the LLDPE base resin and the polymer of the black masterbatch are cross-linked via the silane composition.

Strict quality control system. More specifically, the invention has to do with silane cross-linked track resistant insulation comprised of linear low density polyethylene, carbon black, an antioxidant and UV inhibitors.

The resulting close-proximity configuration minimizes the amount of space and hardware required for line installation; Particularly useful in congested areas such as alleyways or tight corridors.
