It is designed for use in heating and air conditioning control circuits and alarm systems. The conductors are insulated with polypropylene and protected by a brown PVC (polyvinyl chloride) outer jacket. Rated for a maximum of 150 volts and suitable for temperatures up to 140 degrees F, this wire is classified as a Class-2 Power-Limited Circuit Cable. It is UL listed and CSA certified, covering both domestic and Canadian installations.\u003c\/p\u003e\u003cp\u003eThis thermostat wire is suited for residential and light commercial HVAC applications where a multi-conductor low-voltage control cable is required. The sunlight-resistant jacket makes it appropriate for both indoor and outdoor runs, including exposed exterior routing between equipment. Alarm and security system installers also use this wire for bell and signal circuits. The 250-foot roll format is practical for larger jobs or multiple runs from a single spool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18 AWG, 7-conductor solid copper construction for reliable low-voltage signal transmission\u003c\/li\u003e\n\u003cli\u003eClass-2 Power-Limited Circuit Cable designation suitable for HVAC control and alarm wiring\u003c\/li\u003e\n\u003cli\u003ePolypropylene conductor insulation with brown PVC outer jacket\u003c\/li\u003e\n\u003cli\u003eSunlight-resistant jacket rated for indoor and outdoor installation\u003c\/li\u003e\n\u003cli\u003eRated up to 140 degrees F and 150 volts maximum\u003c\/li\u003e\n\u003cli\u003eUL listed and CSA certified\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 18\/7 low-voltage thermostat cable compatible with residential and light commercial heating, cooling, and alarm control systems requiring a Class-2 rated, multi-conductor wire.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of low-voltage thermostat and control wiring is typically performed by licensed HVAC technicians or electricians. Always de-energize the control circuit and disconnect power to the air handler, furnace, or condensing unit before pulling or terminating new wire. Class-2 wiring must be installed in accordance with NEC Article 725 requirements regarding separation from power conductors and permitted wiring methods. Avoid sharp bends or pinching the cable during routing to maintain jacket and insulation integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor\u003c\/strong\u003e: 18 AWG Solid Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Conductors\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Length\u003c\/strong\u003e: 250 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 150 volts maximum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 140 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Material\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJacket Material\u003c\/strong\u003e: Brown PVC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Classification\u003c\/strong\u003e: Class-2 Power-Limited Circuit Cable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSunlight Resistant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL Listed, CSA Certified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Format\u003c\/strong\u003e: Roll\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.25 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOUTHWIRE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 64170444\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWIRE","offers":[{"title":"Default Title","offer_id":51347946275122,"sku":"64170444","price":172.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310548132.jpg?v=1782116549","url":"https:\/\/voomisupply.com\/products\/southwire-64170444-18-7-solid-copper-thermostat-wire-250-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
