An integrated equipment platform with platform base, corner post, and roof- to support modular equipment rack/cabinets and power distribution and pre-wiring. The platform is designed to be transported fully assembled including equipment cabinets/racks and could also be used to deliver additional required site materials to site in a single shipment to the site to save costs. The integrated equipment platform can be field expanded by installing additional modular cabinets or equipment and or by connecting it to other integrated equipment platform expansion model.

Provided is an RF heat dissipation plastic. The heat dissipation plastic according to one embodiment of the present invention is implemented by including: a polymer matrix comprising a base resin; and hollow first fillers dispersed in the polymer matrix. Accordingly, the RF heat dissipation plastic has the advantageous effect of simultaneously exhibiting low permittivity and excellent mechanical strength due to the hollow fillers included therein. In addition, despite the low permittivity and excellent mechanical strength designed for the RF heat dissipation plastic, the RF heat dissipation plastic exhibits excellent heat dissipation performance due to non-hollow fillers included therein, which exhibit heat dissipation performance. According to the present invention, the RF heat dissipation plastic exhibiting the low permittivity and the excellent mechanical strength and heat dissipation performance can minimize performance degradation or functional loss of a repeater cabinet which may be affected by transmission and reception of high-frequency band signals according to permittivity, and thus can be widely applied to various products across all industries.

The invention relates to a switch cabinet arrangement with at least one IT rack or switch cabinet housing and with at least one cooling device, which has an air-liquid heat exchanger for cooling components accommodated in the IT rack or switch cabinet housing with cooled air, wherein the air-liquid heat exchanger comprises a first flow for cooled liquid and a first return for heated liquid, wherein the cooling device comprises a liquid-liquid heat exchanger, to the second flow of which the first return of the air-liquid heat exchanger is connected. A corresponding method is further described.
