Technical Terms

Composition and meaning of shell protective grade (IP code), Quoted from GB4208-2008、IEC6052 The purpose to specify the shell protection grade for electrical equipments is to prevent human body approach to internal dangerous parts, prevent solid impurities entering equipment shell and prevent harmful damage to equipments for water in shell. Composition and meaning of IP code (International Protection) IP code is composed of code letter IP (International Protection), the first digit and others (See Table 2 for the composition of IP code)

Enclosure

The system adopts excellent alloy as enclosure material,enjoys non-magnetism,environment protection,light weight and fast heat dissipation capability.No-eddy current loss when system on loading.Airproof sealing parts for assembly keep the high IP capacity;Top and bottom aluminum extruded profile provide high strength and better locating.The surface is static painted and passed the 1200h salt withstand test,which can meet the high air humidity,salt separating,high pollution etc.Environment.

 

Conductor

The conductors of the RM busway system are normally tinplated or silver plated,totally covered with highly insulation material.

XMMX-XL C is copper system;XMMX-XL A is aluminum system.Aluminum conductor should be nickel-plated and copper-plated before tin-plated.
