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. In most instances high voltage portable work can be achieved through the usage of either dressing; it is just important to check which dressing is most appropriate for the job at hand.<\/p>\n<h2>Approvals &amp; Standards<\/h2>\n<p>Type W cable possesses numerous certifications that guarantee its success in many applications:<\/p>\n<ul>\n<li>UL 1650 \u2014 This is the portable power cable standard.<\/li>\n<li>UL Type W listing \u2014 Rated for 2,000V in any configuration.<\/li>\n<li>UL dual rated RHH\/RHW \u2014 indicates that the single conductors are rated for 600V as general building wire.<\/li>\n<li>MSHA flame test \u2014 Approved for mining use (needed for underground applications).<\/li>\n<li>ICEA S-75-381 \/ NEMA WC-58 \u2014 They are recognized portable cables standards.<\/li>\n<li>CSA approval \u2014 The Canadian qualification.<\/li>\n<li>RoHS \u2014 This means that the restricted hazardous substances are not present.<\/li>\n<\/ul>\n<p>If your project is connected to MSHA, you will need Type W cable \u2014 SOOW won\u2019t make it through the inspection.<\/p>\n<h2 id=\"choose\">How to Choose: Type W or SOOW?<\/h2>\n<p>Proceed to ask the following questions in order:<\/p>\n<ul>\n<li>What is the required voltage for the equipment? 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. Typical pricing estimates per foot for 2025-2026 (for multi-conductor copper wire) is as follows:<\/p>\n<table>\n<thead>\n<tr>\n<th>Conductor Size<\/th>\n<th>Typical Price per Foot<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>8 AWG (3-4 conductors)<\/td>\n<td>$4-$8<\/td>\n<\/tr>\n<tr>\n<td>6 AWG<\/td>\n<td>$6-$12<\/td>\n<\/tr>\n<tr>\n<td>4 AWG<\/td>\n<td>$8-$16<\/td>\n<\/tr>\n<tr>\n<td>2 AWG<\/td>\n<td>$12-$24<\/td>\n<\/tr>\n<tr>\n<td>1 AWG<\/td>\n<td>$15-$30<\/td>\n<\/tr>\n<tr>\n<td>1\/0 AWG<\/td>\n<td>$18-$38<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Different pricing applies depending on the wiring installation, based on the conductor number, insulation material, and supplier; however, the cost is lowered greatly when purchased in bulk from the wire distributor.For buyers building distribution systems around portable power \u2014 generators, transfer switches, and the protection gear behind them \u2014 pairing the right cable with the right <a href=\"https:\/\/huyuglobal.com\/vi\/blog\/what-is-mccb-and-mcb\/\" rel=\"nofollow\">MCB\/MCCB protection<\/a> and a certified <a href=\"https:\/\/huyuglobal.com\/vi\/blog\/what-is-ul-489-breakers\/\" rel=\"nofollow\">UL 489 breaker<\/a> keeps the whole power chain safe and code-compliant \u2014 and when a breaker eventually needs replacing, the costs in <a href=\"https:\/\/huyuglobal.com\/vi\/blog\/how-much-to-replace-a-circuit-breaker\/\" rel=\"nofollow\">our breaker replacement guide<\/a> help you budget the job.<\/p>\n<h2 id=\"faq\">C\u00e2u h\u1ecfi th\u01b0\u1eddng g\u1eb7p<\/h2>\n<h3>What is the main difference between Type W and SOOW cables?<\/h3>\n<p>The differences between them consist of their ratings and durability: Type W has a tough portable power cable rated for extreme use with voltages of up to 2,000V thanks to its thick layers of EPDM insulation and CPE jacket while SOOW is a more flexible and less costly cable rated for 600V use. 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>T\u00e0i li\u1ec7u tham kh\u1ea3o<\/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>K\u1ebft lu\u1eadn<\/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.
