Disc suspension insulator is an assembly of one or more shells with metallic fittings. They are nonrigid supporting type. It can be divided into ball & socket type and clevis & tongue type. This structure enables them form the insulator string by fitting into themselves one another as per voltage requirement. A suspension insulator set complete with the fittings is used to carry a line conductor or conductors at its lower end. The top is fixed to the crossarm of the tower.
The features of disc insulator
◆ The head portion of ball pin and cap are suitably designed so that when the insulator is under tension the stress are uniformly distributed as compression over the pin hole portion of the shell ◆ Disc insulator is designed, manufactured and tested in accordance with insulator standard / insulator specification ◆ Disc insulator and insulator end fittings come in contact with cement ◆ Usually made from porcelain material ◆ Normally used on transmission power lines Disc insulator can be designed in accordance with ANSI C29.2 and IEC 60305 standards, the code number of Disc insulator ◆ ANSI C29.2 specification: ANSI 52-1, ANSI 52-2, ANSI 52-3, ANSI 52-4, ANSI 52-5, ANSI 52-6, ANSI 52-8, ANSI 52-9A ◆ IEC 60305 specification: U40B, U40BP, U70BS, U70BL, U70BLP, U100BS, U100BL, U100BLP, U120B, U120BP, U160BSP, U160BS, U160BL, U160BLP, U210B, U210BP, U300B, U3000BP, U400B, U500B, U70C, U70CP, U100C, U100CP, U120C, U120CP, U160C, U160CP, U210C, U210CP

Packing & Delivery
The methods employed to pack composite insulators are the result of experience gained from shipping millions of insulators to user warehouses and construction sites in a large number of countries worldwide.The packing method illustrated below have been developed to minimize possible damage during shipment and storage as well as to reduce space and freight cost. The separators are made by wood.
