Temperature rise test lamp holder
1. Material requirements of lamp holder for lamp holder temperature rise test:
(1) Composition: Nickel with a purity of over 99.5%;
(2) Structure and characteristics: the grains of the material should be fine and have regular structure, and the grain size: the minimum value is ASTM8 (the maximum value is no more than 0.019mm); The electrical conductivity is 22.6% iacs; The resistivity at 200C is microhm. cm: 7.63 ohms/cir. mil/ft: 45.9; Heat conductivity cal/cm.2sec.0c/cm.at700c: 0.206btu/ft.2/HR/0f/ft.at1580c: 49.9; Temperature coefficient 200-1000c/0c, 0.0058 200-5000c/0c, 0.0074 200-8000C／0C 0.0060； 0.0060;
(3) The thickness is 0.5 mm ± 0.02 mm;
(4) Vickers hardness: HV=135 ± 15;
(5) Quality and roughness: The composition and characteristics of materials should be consistent. Roll the nickel sheet into a smooth cylinder with a smooth surface. Sleeves should be cut longitudinally, and there should be no bending, waviness, indentation, inclusions, grease and other defects.
2. Material requirements of spring
Elastic steel wire, diameter: about 0.8 mm, length: 1 ~ 1.5 turns around the sleeve.
