Cable Calibration Equipment

Overview

Cable check and cable, cable lookups are a bit a bit of arbitrary wiring (no need to publicly line). It can greatly improve the construction progress, which is a new test tool in on-site construction such as electricity, telecommunications, automation control.

The cable calibration equipment is based on the characteristics of foreign new types of wire tools, combined with the actual situation of China, using digital identification technology, making the test work simple and accurate.

1. Application

It is used to evaluate the ability of vertically installed bundle wires or cables to suppress flame vertical spread under specified conditions. This equipment is widely used in wire and cable industry, colleges and universities and commodity inspection departments.

The experimental device is a self-supporting box with length of (1000±100) mm, width of (2000±100) mm and height of (4000±100) mm. The bottom of the box is above the ground. The circumference of the test box is sealed, and the air flows into the box from an inlet of (800±20) mm x (400±10) mm, Open a vent (300±30) mm x (1000±100) mm at the rear of the top of the box. Thermal insulation with heat transfer coefficient of 0.7Wm2K1 is adopted on the back wall and both sides of the test box.
