Technical parameters and structure dimensions

Product features and Performance test

Characteristic:
1.Easy installation ,Strong corrosion resistance,good conductivity,cost low
2.Has a bronze look, not easy to change surface color.
3.Part number and conductor range marked on part for easy identification
4.True hex design for body and nut hex to provide correct fit with socket, box or open end wrenches resulting in proper torque of electrical connection
5.Pressure bar to provide secure connection on a full range of conductor combinations used with each connector assuring premium wire pull-out strength
Performance test:
1.Mechanical performance:the grip force of the wire clamp is 1/10 bigger than the break force of the lead. It comply with GB2314-1997
2.Temperature rise performance: under the conditìon of big current, the temperature rise of connector is less than that of connection lead.
3.Heat circle performance:confirms to GB/T2317.3-2000,the beat circle trial standard for electric fitting.
4.Waterproof insulatìon performance:confirms to the relevant requirements in Part 2 of GB/TI3140.4-1998,
5. Resistance to corrosion performance: under the conditìon of SO, and salt fog, it can do three tìmes of fourteen days circle testìng.
6. Environmental aging performance:under the circumstance of ultraviolet, radiation, dry and moist, expose if with change of temperature and beat impulse for six weeks.
7.Fire-proof performance: insulation material of the connector withstands glowing filament test.
