Low Smoke Zero Halogen - General Information
Why Low Smoke Zero Halogen?
Standard power cable jackets are made from a PVC compound containing Chlorine (part of the Halogen Group), which, when burned release a toxic gas that can cause serious damage to humans and electrical equipment. This raises concerns in applications that have dense PVC cabling where electrical equipment or people are present. Low Smoke Zero Halogen, also known as Low Smoke Free of Halogen or (LSZH, LSOH, LS0H, OHLS) refers to the cable jacketing which is composed of thermoplastics/thermoset compounds that release limited smoke and no halogens when exposed to high heat/fire. This cordage was initially invented to solve two main problems: reduce smoke/improve visibility in an emergency fire escape situation and reduce toxins being released in such a fire that could harm victims exposed. This cordage is generally used where there is limited ventilation or where set standards require such health/safety measures. You can find the amount of halogen contained in typical LSZH Cable in Table 2 below.
Common Abbreviations and Terms for Low Smoke Zero Halogen
|LSZH||Low Smoke Zero Halogen|

Halogen Content in Standard Wire & Cable Polymers
Using the table below, you can see that standard PVC cables contain vastly greater amounts halogen contents that any of the LSZH polymers.
|Polymer||Halogen Content % by Weight|
|EPR (Ethylene propylene rubber)||<.02|
|XLP (Cross-Linked Polyethylene)||<.02|
|CSPE (chlorosulfonated polyethylene)||13-26|
|CPE (chlorinated polyethylene)||14-28|
|PVC (polyvinyl chloride)||22-29|
|FEP (fluorinated ethylene propylene)||62-78|

When should I use LSZH cabling?
Low Smoke Zero Halogen cabling is usually used in regulated industries such as government. New data centers are sometimes choosing to use LSZH cabling to help protect data center facilities from the harmful smoke in case of fire. Because data centers utilize large ventilation systems, even a small amount of smoke in a small area can quickly be distributed accidentally throughout the entire building through the ventilation systems. A side note is the National Electrical Code requires cables used in plenum spaces to be Low Smoke Emitting, which is another common usage of this cordage. Refer to the National Electrical Code(NEC), or the National Fire Protection Agency(NFPA) to determine if LSZH cordage is right for you.
IEC 60320 C19 CONNECTOR (FEMALE)
The IEC 60320 C19 is a grounded 3 Wire connector rated up to 250V and 20 Amps. The C19 can be found on a variety of power cords, including NEMA to 320 Adapter cords, and International Plug types to IEC 320 connectors, but the most common application is the IEC 320 C20 to C19 power cord which is a a standard extension cord used to power high powered IT Equipment. The C19 is typically used in high powered blade server chassis, large network routers, and other IT equipment that draws more power than a standard C13 can accommodate.
What does the IEC 60320 C19 Connect to?
|The IEC 60320 type C19 connector is designed to connect to the IEC 320 C20 plug and Inlet. THE C20 Plug is commonly found on power cords used in the data center industry. The C20 Inlet can be found on a variety of high powered IT Equipment ranging from switches to Un-Interrupted Power Supply systems.|
IEC 60320 C20 PLUG (MALE)
The IEC 60320 C20 is a grounded 3 Wire Plug rated up to 250V and 20 Amps. It is commonly used with either 14awg or 12awg conductors, depending on the application and the power draw required for the device. The most common configuration for a C20 is in a jumper cable scenario, providing power from a PDU to a blade server chassis, high powered server, large network router, or similar device. The C20 is used in applications where the most common IEC320 plug, the C14 will not provide enough power. This plug is rated for temperatures up to 65*C. For applications where the temperature of the equipment exceeds 65 degree C, we recommend using the high tempature version: The IEC 60320 C22 High Temperature plug, which is rated for temperatures up to 155*C.
What does the IEC 60320 C20 Plug into?
|The IEC 60320 type C20 Plug is designed to connect to a standard IEC 320 C19 connector or Outlet. The connector is commonly found on power cords, and the outlet is commonly found on Power Distribution units.|
