Firstly, the cable should not be tested until permanent seals have been fitted to both ends of the cable. An insulation test carried out 24 hours after the cable has been terminated, should achieve a value in excess of 100 M??.

As previously stated, the cables are made from inorganic materials and therefore do not deteriorate with age. There are many installations throughout the world that are over 50 years old and the cable is in perfect condition. In some cases, on very old installations the original neoprene conductor insulating sleeves may have deteriorated but it is a comparatively simple matter to renew these with the present day standard sleeving. Advice on this matter can be obtained from our Prescot address. See similar questions...

Pyrotenax cables are suitable for burying in the ground and are subject to the same procedures as other cables regarding the depth of trench, mechanical protection and identification of routes. We would always recommend plastic covered cable as some soils can contain elements corrosive to copper. See similar questions...

Electrolytic action may take place when the coppersheath is in contact with the galvanised (zinc) plating of the cable tray. The reason for this is that the electropotential series indicates that zinc is anodic to copper and therefore preferential corrosion of the zinc plating may occur. This action will not effect the Pyrotenax cable sheath, but may cause superficial corrosion of the cable tray. See similar questions...

Tile roofs are good insulators. The combined effect of the roof tiles, decking and the air space between the tiles allows for better air circulation and thereby reduces direct heat transfer. This results in lower air conditioning costs in the summer and decreases the formation of ice dams in the winter. BACK TO TOP See similar questions...

Most ceilings are installed between floors that are maintained at the same temperature - making insulation unnecessary. Basement recreation rooms are at least partly heated by heat flow through the ceiling from the heated space above. In that case, attempting to insulate the basement ceiling surface could actually reduce heat flow. See similar questions...

The R-value is the measure of the resistance of a material to heat flow (or heat gain) by conduction only. The k-value is the measure of thermal conductivity; it measures the rate of heat transfer by conduction through a material from face to face. ASTEC's thermal conductivity (k-value) is very low (0.00345 W/m ?K or 0.00199 Btu/h ft ?F). A very low k-value indicates a good conductive insulator. See similar questions...

After scheduling your free evaluation and estimate, one of our highly qualified and trained prefessionals will meet you on-site, where they will take measurements, evaluate the project and make recommendations if warranted and/or requested. Following the evaluation, a proposal will be submitted. Upon acceptance of the proposal, we will then contact you a couple of days prior to our arrival so that you may prepare for the installation. See similar questions...

Since your kitchen will be out of commission for one to two weeks, expect to eat at restaurants frequently – a minor inconvenience that is more than made up for when the installation is complete! See similar questions...

Many DSL modems have NAT router functions incorporated, which most cable modems generally do not have. If the NAT router function of your DSL modem does not support SIP pass-through, or is not SIP friendly, you may need to configure the DSL modem to act as a bridge. This can also be true with modems that have certain built in firewall features, which prevent some VoIP signaling and voice traffic. See similar questions...

Ideally, you uninstall the cable and return it to Gore for repair or replacement. However, we recognize that this is not always possible. Gore has resources available to perform repairs at your facility. In most cases, we can begin the repair within 48 hours of notification. We recognize the critical nature of the flight integration schedule and are prepared to meet your needs. See similar questions...

Yes. A resistance reading can be taken with an ohmmeter. Insulation resistance can be verified with a megger. Do Not energize the cables prior to installation. See similar questions...

PUR-polyurethane for building applications resists to a maximum temperature of +100?C, PIR-polyisocyanurate foam insulation on the other hand resists to +130 up to 150?C. However, the foam can briefly resist to higher temperatures during the processing, for instance when bonding the roof insulation board Bi3 with hot bitumen. All Eurothane products have a product approval ATG/H and generally also an ATG system approval. See similar questions...

ANSWER: Yes, the MEG-ALERT will check submersible pumps and the underwater cables from the starter to the motor. See similar questions...

ANSWER: Yes, by installing our ground interrupter on each grounded generator equipped with a MEG-ALERT, to remove all grounds before automatically testing insulation resistance. Two safety circuits are provided to ensure that the ground is re-connected before the generator can produce voltage. See similar questions...

ASTEC is always applied with a dry film thickness (dft) between 12 mils (305 microns) and 15 mils (382 microns). Any additional thickness will be wasted because the principle of solar radiation control has nothing to do with thickness but everything to do with solar reflectivity and thermal emissivity.

Superior Walls offers two wall systems. The original R5 wall is built with a continuous layer of 1" Styrofoam and has an R-value of 5. The Xi wall system is built with a continuous layer of 2.5" Styrofoam, resulting in an R-value of 12.5. Additional insulation can be added between the studs for a total of R-24.

R-value is derived from a controlled laboratory test of insulation’s resistance to conductive heat flow. BioBased 501 has an R-value of 3.83/inch. See similar questions...

Heritage has a standard R-20 wall insulation value. Heritage standard attic value is R-40. You may choose to Super Insulate your new home by increasing the walls to R-25 and the attic to R-50. See similar questions...
