500-3 ASD-VFD Tray Cable

One of the cables most often used with variable frequency drives (VFDs) is a ASD-VFD tray cable. The 500-3 option of this cable is manufactured to meet a number of different regulations and the guidelines of the National Electrical Code. These guidelines include UL Standard 1277, IEEE 383, IEEE 1202 / CSA FT-4, and ICEA T-29-520. They are also rated for use underground, including direct burial, and are RoHS compliant.

Description:

3 conductors, stranded, insulated with heat and moisture resistant cross-linked polyethylene, phase identified, cabled together with suitable fillers and 3 symmetrical bare copper ground conductors. Cable core covered with 5-mil helical copper tape shield, and overall flame and sunlight resistant black PVC jacket. Surface printed. Jacket available in colors.

• Temperature Rating: 90?C Wet / Dry ICEA S-95-658 / NEMA WC-70
• Exposed runs rated #4 and larger 600 Volt Tray Cable RoHS Compliant.

Specifications:

This type of cable makes use of stranded conductors that have a stranding (Al/Stl) of 37. The cable features three conductors and three bare copper ground wires. The conductors have a size of 500 AWG, while the grounds have a size of 1 AWG. These wires and conductors are all protected by a cross-linked polyethylene insulation that has a nominal thickness of 65 mm. This insulation is heat and moisture resistance. The core of the cable is also protected by a special 5-mil helical copper tape shield. On top of all of this, there’s a sunlight resistant and flame resistant PVC jacket over everything. This jacket comes in a variety of colors (black is standard) and has a thickness of 110 mils.

The overall cable diameter is 2.271 inches, and its overall allowable ampacity is 430 amps. It’s rated for 600 volts.

Applications:

The 500-3 ASD-VFD cable is designed for use as a connecting cable for variable frequency drives and AC motors. These cables control the speed and the torque of the motor by varying the motor input frequency and the voltage. This reduces the amount of power needed and also helps improve the overall performance. There are a number of different electro-mechanical drive systems such as fan motors, water pumps, and conveyor belt motors.

These cables can be used in the following locations:

• Wet and dry environments
• Locations where the standard operating temperature of the conductors will not be above 90 degrees C
• NEC Hazardous Locations designated Class I, Div. 2; Class II, Div. 2; and Class III, Div. and Div. 2.
