High Performance Mesh-type Basic Electrical Maintenance Training and Assessment Device Single Sided Double Group Electrician Skill Teaching Equipment

Product Introduction

The RM-F144 mesh-type basic electrical maintenance training and assessment device consists of a multi-functional mounting plate (mesh plate) made of steel plate, a training platform, and a power supply unit. Various components, devices, and parts selected for training can be easily and flexibly installed on the mesh plate.

Different components, devices, and parts can be selected according to teaching and training needs to conduct training for different course modules and projects. The RM-F144 mesh-type basic electrical maintenance training and assessment device has a wide range of applications and can complete a variety of teaching contents and training projects. Used components, devices, and parts can be removed from the training platform and centrally stored, minimizing damage and loss. One training space can complete the teaching and training of several majors, making it economical and practical. For schools with limited training space and restricted teaching funds, the RM-F144 mesh-type basic electrical maintenance training and assessment device is an ideal vocational education training equipment.

Equipment structure and function

This training platform consists of three main parts: a training screen (with built-in power supply), a training table, and a training storage cabinet.

1. The training table is supported by four industrial aluminum profile columns. Adjustable feet can be installed at the ends of the columns for easy height adjustment. The main structure is connected by two C-shaped aluminum die-casting components on each side. The tabletop height is approximately 800mm. A support frame with a cross-sectional dimension of 30*30mm is provided under the tabletop, capable of bearing a load of no less than 300kg. The columns are made of industrial aluminum profiles with an oxidized surface treatment. The cross-sectional dimension is 70*70mm, with grooves on all four sides, each groove approximately 8mm wide. Plastic plugs are fitted at the ends, and universal nuts and accessories for industrial aluminum profiles are used in the grooves. The C-shaped aluminum die-casting components are symmetrical on the left and right, made using a die-casting process, and then machined, shot-blasted, sandblasted, and finished with a blue electrostatic powder coating.

2. The training tabletop is made of 25mm thick, high-density, light gray laminate with specially designed edges, effectively improving the insulation level. The bottom of the table is equipped with at least four guide wheels for easy movement.

3. The training storage cabinet is made of cold-stamped sheet metal with rounded edges, featuring a closed structure and electrostatic powder coating. Dimensions: approximately 450mm wide x 420mm deep x 550mm high, total weight ≥31kg. The cabinet has rounded edges (R=30mm) on all four sides, with a frame thickness ≤2.5mm. It features heavy-duty, snap-on three-section rails with a load-bearing capacity ≥30kg. Drawer handles use a snap-fit sheet metal edge-rolling process, and the drawers have a locking mechanism. The bottom is equipped with four universal casters with brakes.

4. Two perforated panels: precision-machined using a CNC punching machine, with a reasonable and uniform mesh distribution and consistent aperture. Components that can be installed on these panels include various low-voltage electrical components, PLCs, microcontrollers, frequency converters, touch screens, etc. The thickness of the perforated plate is 1.5 mm.
