What separates Type W from Type G however is that Type G constructions typically come with grounding conductors as part of the package while Type W depends on the conductor arrangement that has been specified to achieve grounding.

For any voltage greater than 600V, Type W is the choice. For voltages equal to or below 600V, both options would suffice.<\/li>\n<li>How severe is the working environment? If mining is involved (severe pressure from rocks, equipment being dragged over cables, heavy crushing etc.), it is advisable to go with Type W since its jacket is thicker.<\/li>\n<li>Do you need permission from MSHA? If the application is taking place underground, choose Type W.<\/li>\n<li>How flexible should your cable be? If flexing around tight corners, twisting and turning is required, it is preferable to go for SOOW.<\/li>\n<li>Working under how much money? Type W has a higher price than SOOW, if less than 600V is needed, choose SOOW.<\/li>\n<\/ul>\n<h2>Safety &amp; Usage Rules<\/h2>\n<ul>\n<li>Examine before every use \u2014 look for any damage such as cuts, scrapes, compression areas, or exposed wires; Type W is durable, but it is not indestructible.<\/li>\n<li>Do not use as a permanent building wire within walls \u2014 it is a portable wire; for permanent electrical work, the wiring used is THHN\/THWN with conduit.<\/li>\n<li>Do not direct bury unless the construction is designed to be buried \u2014 check the jacket markings and local requirements.<\/li>\n<li>Choose the correct ampacity according to the load \u2014 Type W wire can take 2,000V but this refers to the voltage capacity and not the ampacity.<\/li>\n<li>Prevent damage \u2014 use ramps or elevated ways where trucks and cars travel on the cable; avoid putting the cable in standing and stagnant water.<\/li>\n<li>Scrape off the oil and other chemicals immediately after the cable is overexposed to them \u2014 the coat of the cable can be oil-resistant, but it will hold longer without these chemicals.<\/li>\n<\/ul>\n<h2>Prices &amp; Where to Buy<\/h2>\n<p>The reason behind the higher price of Type W in comparison to SOOW is that Type W uses more copper and heavier insulation material.

Type W is also MSHA-approved for use in mines. Use SOOW at less than 600V if flexibility is required; choose Type W for any higher voltage or maximum durability.<\/p>\n<h3>Does SOOW cable need to be in conduit?<\/h3>\n<p>NO \u2013 SOOW is a service cord that makes it possible to operate without conduit&#8217;s help in a flexible application (NEC Article 400). Its use for permanent installation is not permitted, and it is not approved for underground installation. Permanent installation requires the use of building wires (THHN\/THWN) and conduit, while SOOW can be employed for portable power supply tasks.<\/p>\n<h3>What voltage is SOOW rated for?<\/h3>\n<p>SOOW has a voltage rating of 600 volts (plus 300V versions referred as junior SJOOW). SOOW cable can be used for applications involving most power tools, motors as well as machinery. However, Type W cable is required for higher voltage systems as well as for mining operations requiring MSHA approval.<\/p>\n<h3>Can Type W cable be used as building wire?<\/h3>\n<p>Single conductor Type W is a dual rated cable with both RHH and RHW ratings up to 600 volts. For this reason, single conductor Type W can be used as industrial hook-up wire in conduit up to 600 volts. However, while multi-conductor Type W is meant to be used for temporary power, using this type for permanent installation is not recommended. Always check local codes in accordance to the specific use of the cable.<\/p>\n<h2>\u0e2d\u0e49\u0e32\u0e07\u0e2d\u0e34\u0e07<\/h2>\n<ol>\n<li><a href=\"https:\/\/www.awcwire.com\/power-cable-and-portable-cord\/type-w\" rel=\"nofollow noopener\" target=\"_blank\">Allied Wire &amp; Cable \u2014 Type W Cable Specifications and Applications<\/a><\/li>\n<li><a href=\"https:\/\/www.ul.com\/\" rel=\"nofollow noopener\" target=\"_blank\">UL \u2014 UL 1650 Portable Power Cable Standard &amp; Type W Listing<\/a><\/li>\n<li><a href=\"https:\/\/www.msha.gov\/\" rel=\"nofollow noopener\" target=\"_blank\">MSHA \u2014 Mine Safety and Health Administration Cable Requirements<\/a><\/li>\n<li><a href=\"https:\/\/www.nfpa.org\/codes-and-standards\/nfpa-70-standard-development\" rel=\"nofollow noopener\" target=\"_blank\">NFPA 70 (NEC) \u2014 Article 400 Flexible Cords and Cables<\/a><\/li>\n<li><a href=\"https:\/\/www.nema.org\/\" rel=\"nofollow noopener\" target=\"_blank\">NEMA \u2014 NEMA WC-58 Portable and Power Feeder Cables<\/a><\/li>\n<li><a href=\"https:\/\/www.automationdirect.com\/flexible-portable-cord\" rel=\"nofollow noopener\" target=\"_blank\">AutomationDirect \u2014 Portable Cord and Type W Selection Guide<\/a><\/li>\n<\/ol>\n<h2>\u0e2a\u0e23\u0e38\u0e1b<\/h2>\n<p>Type W is the UL designation used for the heavy-duty flexible power cable that is sought after in industrial environments when the task is major and the surroundings difficult: rated for 2000 volts, made of the EPDM rubber material and CPE plastic, able to work in the temperature range from -40 to +90 degrees Celsius, MSHA compliant for mining applications. The \u201cW\u201d refers to the type of the cable and not to the \u201cwater resistant\u201d W in SOOW, which is a different cable type working on 600 volts with higher flexibility and lower cost.
