Most power cables that are made for standard indoor use would not last long outdoors under the elements or even indoors on a factory floor. That’s why TC-ER power cable was developed.
TC-ER stands for “tray cable − exposed run.” It is a rating for a type of electrical cable that is specifically designed for use in industrial and commercial applications where the cable will be exposed to harsh conditions such as moisture, heat, and mechanical stress.
This blog post describes several main functions of TC-ER – namely, powering DC Defenders, AP antennas, and factory automation – and the benefits of buying this type of cable in bulk spools. It concludes with information about Transtector’s new line of TC-ER bulk cable.
Performance Requirements of TC-ER
TC-ER-rated power cable is commonly used in cable tray systems and raceways, where it can be run exposed without the need for a conduit or other protective covering. It often powers devices that are high atop towers, such as antennas, as well as control motors, pumps, and other equipment in manufacturing plants, chemical processing facilities, and other industrial applications.
To carry the TC-ER rating, the power cable must be rated for use in wet and dry locations, be resistant to sunlight, and have a minimum bend radius for installation. Additionally, exposed-run tray cable must be able to withstand mechanical impact, such as being stepped on or run over, and resist damage from chemicals and oils.
Following are details about three of the many uses for exposed-run tray cable.
Powering DC Defenders
One common use for TC-ER is to power DC Defender surge protection devices. DC Defenders protect sensitive electronic equipment and systems from power surges and electrical transients caused by lightning strikes, power fluctuations, and other electrical disturbances. They are commonly used in applications where DC voltage is used, such as solar panel installations, telecom systems, and industrial automation systems.
To power DC Defender SPDs, exposed-run tray cable is typically run from a power source, such as a DC power supply or battery bank, to the location of the surge protection device. The cable is often installed in a cable tray or conduit for support and protection.
Exposed-run tray cable is well-suited for use with DC Defender SPDs because it is designed to handle high-voltage and high-current applications, and is resistant to damage from harsh environmental conditions.
Powering AP Antennas
Another popular use for TC-ER is to connect with an antenna with a high-power access point (AP). An AP is a wireless networking system that consists of an antenna with a high gain and an access point that has a high transmitting power. The high-power AP allows the access point to transmit a stronger signal over a longer distance, providing greater coverage and improving the overall performance of the wireless network.
To power AP antennas, the exposed-run tray cable is typically run from a power source, such as a battery or DC power supply, directly to the antenna. If the AP antenna supports PoE, the TC-ER cable may be able to be used to power the Ethernet PoE switch or injector.
Powering Factory Automation
Exposed-run tray cable is useful with factory automation for several reasons. It is rugged enough to withstand not only mechanical impact and movement but contact with chemicals, oils, and heat. Another factor is its ability to interface with terminal block power, which is commonly used in industrial control systems, automation equipment, and power distribution applications.
To power factory automation equipment, TC-ER is typically run from a power source, such as a power distribution panel or motor control center, to the location of the equipment. The cable is often installed in a cable tray or conduit for protection and support.
TC-ER can be used to transmit data signals in addition to power, making it possible to control factory automation equipment remotely and monitor its performance.
Benefits of Bulk Power Cable
A key feature to look for in exposed-run tray cable is for it to be offered in bulk lengths. This ensures that it can cover longer distances, such as for tower runs, and that you can cut custom lengths in the field instead of having to determine the exact lengths you will need ahead of time.
Two other benefits of buying TC-ER in bulk are cost savings, especially for large-scale projects, and reduced downtime from having cable on hand for repairs.
