Tray Control Cable THHN/PVC 600V 8 AWG - 750 MCM
Tray Control cables are small sized cables used in most control systems. They are designed with a gauge size of 750 MCM and specifically used for transmission and distribution of 600V power. The cable is extensively used various control systems like automotive plants, wind energy, forestry equipment, oil and petroleum equipment, among many more.Since it has a wide range of applications, the cable is designed such as to ensure efficient current transmission, secure insulation and stable functionality. It is therefore constructed with various outstanding specifications which befits the systems of applications. And here below, an outline of the properties of Tray Control Cable:
Tray Control Cable is constructed using copper conductor. Copper is one the largest used electrical conductor in wires and cable products, this is due to its many good properties. Copper is an excellent conductor, strong, hard enough to prevent nicks and also flexible. However, it has some drawbacks and the conductor used in this cable is modified to make it more stable and fit. The modification includes annealing to make it soft and stranding to improve its flexibility and electrical conductivity. The Copper conductor is fully annealed, stranded and bare according to ASTM B3 and ASTM B8. The number of stranding range from 7 to 19 strands while conductors range from 3 to 4.
Tray Control cable has a Polyvinyl Chloride (PVC) insulation which is flame retardant and has clear Polyamide (nylon). Since the cable is to be used in harsh conditions such as in direct burial, it requires a strong, stable and reliable insulation. PVC insulation serves best, it keeps off destructive agents and maintains the conductor structure. The insulation color coding is as per ICEA Method 4.
Cable jackets are addition security features. They complement the insulations to ensure the conductor security is tighter. The Tray Control cable has its jacket made from Polyvinyl Chloride (PVC) with a thickness of about 60 mils. The thicker the jacket the more secure though it causes bulkiness but this jacket doesn’t exceed 60 mils hence less bulky. This jacket system is lead-free, sunlight and flame resistant and environmental friendly.
Tray Control cable has distinctive features:
• It has applied Ripcord
• 600 V rated
• Has THHN or THWN Insulation.
• PVC Jacket
• Copper conductors.
• Excellent resistance to oil, chemical and sunlight.
• Resistance to cold bends and cold impacts
• Tray Control cable has the smallest cable Outer Diameter required for suitable applications
• The crush and impact requirements that this cable has are of Type MC Cable.
• Flame Tests. The cable has gone through the following flame tests: IEEE 383 70,000 BTU/hr and ICEA 210,000 BRU/hr
• It has a color code according to ICEA Method 4
Tray control cable is used in various industrial plants. Generally, the purpose for the cable is power transmission, in controls and also in lighting circuits. It is used broadly in the commercial and industrial applications. Some of the industrial plants where it is applied include: oil and petroleum equipment, processing equipment, packaging facilities, automotive plants and wind energy. The cable is also used in tray wiring, cold temperature storage systems and machine tool wiring.
Thiscable can be used above ground, on raceways or direct burial method. Since it has the capacity to withstand both extreme climates of wet and dry locations, this cable serves well in either of the installation methods. Install it indoors or outdoors, in aerial systems or conduits, in cable ducts, cable trays or directly buried provided the circuit voltage exceeds not 600 volts.
The cable has passed the flame tests by IEEE and is also resistant to oil and other chemicals. These make it sturdy, strong and reliable when used in control systems for oil industries where chances for fire outbreaks are high. Its high flexibility befits it for wind energy and automotive plants where movements are frequent. With high electrical conductivity and stability to temperature variance, the cable makes a good control system.
Tray Control cable has been approved for continuous operation at 900C in dry locations and 750C in wet places. It can sustain a temperature of upto 1300C during emergency overload and 2500C for short circuit conditions. The cable is rated at 600 V.
• UL approved for use continuously in the above mentioned conditions
• Approved for direct burial
• May be used in NEC Class I and II systems
• May be used in Division 2 hazardous locations
• Allowed for Exposed Run (ER) and be used accordance with NEC
Question and Answer:
FAQ - Tray cable control 8 awg 750 awg
Will a tray cable control 8 awg though 750 awg having the smallest cable O.D. be suitable for purposes such as wet locations or direct burial?
Yes, as these cables are in accordance with NEC specifications in regard to wet and dry locations and also direct burial as per Class I, Div. 2 industrial hazardous locations. Moreover, it has the impact and crush requirements as that of Type MC Cable. In addition, it is lead-free and flame retardant even though the outer jacket will be less or equal to 60 mils.
What are the other notable qualities of tray cable control 8 awg 750 awg?
These cables have a flame retardant outer jacket and insulation, which is seen color coded as per ICEA Method 4. It is also resistant to sunlight, heat, cold, oil and grease. It is also permitted for ER or Exposed Run as per NEC specifications. It works well at 900C in dry locations and 75oC for wet locations.
How do I make the tray control cable totally moisture free in wet locations?
Care has to be taken during installation so that moisture does not get inside the cable, although the cables that we get from the market today are tightly packed with no possible space for moisture to seep through. However, when the ends are not sealed properly during installation, you can expect a little bit of moisture to collect.
Why does my cable have a ripcord?
The ripcord serves no other function than to make a neat slit in the outer jacket without damaging the wires inside. After the slit has been made, you can pull away the outer jacket to facilitate installation. Thus, there is hardly any damage done to the cable as well as the inside wires.
Is tray cable control 8 awg through 750 awg the right choice for outdoor and direct burial purposes?
There are many cables in the market along with the tray control cablewhich are well suited for outdoor uses and for direct burial. However, you can choose the tray cable control 8 awg through 750 awg when you want the smallest O.D. which gives you the strength, performance and long-life of cables with bigger O.D. The cables are well tested for all harsh conditions before they come to the market.
What is the unique quality that identifies a tray control cable?
These cables are specially designed for cable trays which are a support element for control, signaling and communication conductors. These cables are basically low-voltage or signal cables and so carry only a limited amount of electric current at a time. So the cables do not have to be spaced apart and they also do not have to be in a single row to dissipate heat.
