A track resistant, non-shielded, electric power cable comprising:. The MOQ of our most cable is meters. Land High Voltage cables.
How can I get a sample to check your quality? The use of a metal deactivator is highly preferred when the central conductor of the electrical power cable is copper.
A 5 kV nonshielded electrical cable constructed of No.
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.
Honestly, it depends on the order quantity and the season you place the order. 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. This discharge can track along the ucea of the cable leading to premature cable failure. The cross-linked insulation material of claim 1 or claim 2wherein said ultraviolet ray inhibitor is selected from the group consisting of titanium dioxide, hindered amine, substituted benzotriazole, and mixtures thereof.
A second batch of KC formulation was prepared so that enough formulation was available to prepare a total of seven rods, identified by the letters A through G. How long can I expect to get the sample? Unaged Physical Properties Tensile Strength, psi min. It was established in Power distribution in medium voltage. These last three components extruded CV continuous vulcanization triple extrusion. The overall mixing time was maintained at 15 minutes and icra torque was increased over previous s-666-524 procedures from mg to mg.
According to the present invention, a combination of polymer resin, antioxidant, carbon black and UV inhibitors, and a method of cross-linking same with silane, has been discovered which produces an insulation satisfying the physical, electrical and non-tracking properties set forth in FAA L for airport lighting cables.
China sample surface China camera free samples China free sample will. Field of the Invention The present invention relates to improved insulation for electrical power cables which has both weathering and track resistant properties. The old organization called out separate standards for polyethylene, ethylene propylene rubber and other insulation materials.
Furthermore, Penfold does not contemplate, teach or suggest a track resistant insulation nor does this reference teach or suggest the use of carbon black or UV inhibitors to achieve track resistance. Cross-linkable semiconductive composition, and an electric cable having a semiconductive coating.
Tree Wire Cable 11 Kv 3layer ACSR ANSI/Icea S-66-524
Enter between 20 to 4, characters. 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. Partially crosslinked ethylene vinyl acetate copolymers with low melt index values and increased tensile strength. The key difference in the new ICEA standards is the way they are organized. Two hundred and fifty grams of the second formulation, KC, whose ingredients had been premixed together, were added to the mixer over a 4 minute period.
Therefore mixing conditions were again modified to try to improve the homogeneity. The hot creep data indicated that the KC formulation had cross-linked. Your Account Username Password. The mixture was then removed from the mixer and extruded into a number of rods under the conditions set forth in Table 6. Another object of the invention is to provide a cost-effective, track resistant insulation by using low cost materials. After making the plaques, about 0. Although preferred embodiments of the present invention have been described and illustrated, it will be understood by those skilled in the art that various modifications may be made without departing from the principles of the invention.

The silane cross-linked polymer insulation also includes UV inhibitors which provide resistance to UV degradation. The method of claim 13wherein said black masterbatch includes a metal deactivator. Crosslinking silane-grafted polymers, e. New standards are organized differently ICEA standards include requirements for conductors, insulation, coverings, and construction details for wires and cables. We usually quote within 6 hours after we get your inquiry. Upon the addition of the silane, vapors were emitted from the mixer chamber.
In another embodiment the invention is a cable comprising a conductor, a conductor shield and the non-tracking cable insulation. Application Used for primary and secondary overhead distribution where limited space is available or desirable for rights of way. Cable insulation system with flexibility, high temperature deformation resistance, and reduced degree of stickiness.
The RPM of the sigma blades was 20 and the torque was mg. Sign in with your Nexans account:
