Choosing Mercury Cables

Pick a cable by what it carries first, then by conductor material, sheath and reel length.

Speaker and audio cable

Speaker cable is graded by its conductors. The 805.850UK uses pure oxygen-free copper with a polarity line and is rated 6A, economy cables such as the 807.055UK use copper clad aluminium (CCA), here 2.48mm² and 25A, and heavy duty cables such as the 801.696UK mix copper and CCA strands. For PA systems, the 801.817UK is a double insulated two core cable for 100V line speakers. Low smoke zero halogen cables such as the 807.096UK have a purple LSZH sheath that reduces thick black smoke and poisonous fumes in a fire. For screened audio, the 803.588UK is a flexible two core lap screen cable and the 804.263UK a four core braided screen cable.

Network and data cable

Most of the network cable comes in 305m lengths. The 808.001UK Cat5e and 808.011UK Cat6 have solid oxygen-free copper conductors and pass Fluke tests at 100m, at 100MHz and 250MHz, while economy versions such as the 808.021UK use solid CCA. The 808.031UK Cat6a has foil-screened pairs and an LSZH sheath, and the 808.050UK Cat7 S/FTP is rated for 10 Gbps at 600MHz. Outdoor cables such as the 808.010UK have a UV resistant LDPE sheath.
