scope:
ANSI/NEMA HP 8 covers specific requirements for cross-linked, modified polyolefin insulated solid and stranded wire designed for the internal wiring of high-reliability electrical and electronic equipment. ANSI/NEMA HP 8 addresses 600 V (Types LS, ZHDM, ZHDH, and ZH) and 1000 V (Type ZHX) wire and permits continuous conductor temperature ratings of -40°C to 90°C, 105°C, or 125°C with either tin- or silver-coated conductors. These types of hook-up wire are used when the following requirements are called for:
a. Moderate temperature resistance
b. Low temperature resistance
c. Good dielectric constant (Types ZHDM and ZHDH)
d. Moderate dielectric constant (Type LS)
e. Good flexibility and flex life when stranded conductors are used
f. Solder iron resistance for easier solder terminations without potential damage
g. Low smoke (Types LS, ZHDM, ZHDH, ZH, ZHX)
h. Zero halogen (Types ZHDM, ZHDH, ZH, ZHX)
i. Low toxicity (Types LS, ZHDM, ZHDH, ZH, ZHX)
j. Low acid gas generation (Types LS, ZHDM, ZHDH, ZH, ZHX)
