產(chǎn)品特點(diǎn) Features

1.鋁合金外殼鑄造成型,表面經(jīng)高速拋丸清理后高壓靜電噴塑,外殼結(jié)構(gòu)緊湊合理, 強(qiáng)度好, 防爆性能優(yōu)良, 表面塑粉附著力強(qiáng),具有良好的防腐性能,外表整潔,美觀大方;
2.現(xiàn)場只須提供電源即可,無須傳統(tǒng)方式的信號或電源總線,大大簡化安裝過程;
3.采用軍用手持送話筒器、操作簡單方便;
4.機(jī)器內(nèi)集成對講電路、電源電路,功率放大電路及本按電路;
5.電纜連接通過電纜夾緊密封接頭,防爆性能可靠。
1.Enclosure is cast with high intensity aluminium alloy, surfaceis sprayed with plastic by high voltage static electricity, afterthe highly impeller cleaning. The structure of enclosure isreasonable, high-intensive and perfect-explosive and the
surface plastic of good adhesive force is excellent in explosion-proof and appearance.
2.it only need power in site. no need of the singnal or the maincable in traditional way, reduce the time of installtion.
3.adopt the Hand-held transmitter in minitary use, easy to handle
4.integrated interphone, power circuit, Power amplifier circuitandincreased sftycircuit in the machine
5.the cable connect the Cable clip tightly sealed joints, excellentexplosion-proof ability
