Structure and working principle

The insulator is composed of porcelain parts, which contain a conductive metal tire or a set of tires, and the tires are installed in a metal cover. To fix the insulator, there is a metal flange directly connected to the porcelain component itself.

Road reinforced insulators manufactured according to GOST 22229-83 and GOST 20454-85.

Insulation material - Electric porcelain sub group 110 GOST 20419-83, in accordance with the requirements of GOST 5862-79.

Insulator reinforcement is made of GOST 1583-93 aluminum alloy.

Insulator guided tires are made of aluminum or aluminum alloy GOST 15176-89.

The contact pins of insulators should be connected to the switchgear bus, wires, and cables through GOST 15176-89 bolts.

The fasteners of the insulator are made of corrosion-resistant material GOST 17412.

The coating for the joints between steel bars and cement shall be enamel PF-115 GOST 6465-76, and the joint thickness shall not be less than 2 mm.

Tire sealing cover - epoxy enamel ED-16 GOST 10587-84.

Insulator IPU-10/630-7.5 UHL1 (square flange)

Rated voltage: 10kV

Rated current: 630A

Minimum bending failure force: 7.5kN

Weight: 9 kg

IPU-10/630-7.5 UHL1 insulation (square flange) is designed for the operation and insulation of conductive components of enclosed distribution devices and complete distribution devices in electrical stations and substations, and for the connection with open distribution devices or transmission lines with frequencies up to 10kV and 100Hz, Suitable for Type I or II atmospheres and enclosed conduits as specified in GOST 15150-69.

Materials used for manufacturing IPU-10/630-7.5 UHL1 insulators (method blue):

1. Insulation Part - Material Ceramic Electrician Group 110, GOST 20419-83

2. Reinforcement aluminum alloy AK 12, GOST 1583-93

3. Diversion tires - aluminum AD0, GOST 15176-89

IPU-10/630-7.5 UHL1 (method blue) is composed of a ceramic component through an insulator, and a rectangular cross-section conductive metal rod (busbar) or busbar group passes through its internal cavity.

For fixing the fuel tank cover or wall with insulator IPU-10/630-7.5 UHL1 (method flange), it is equipped with a metal flange. The flange is connected to the porcelain parts using cement mortar. The guide tire is installed on a metal centering washer or metal cover. The cover and flange are fixed to the porcelain parts with cement sand composition.

Insulator IPU-10/630-7.5 UHL1 (square flange) has a far protruding edge (wing) to protect the lower part of the insulator from the influence of rainwater.

The warranty period for IPU-10/630-7.5 UHL1 (square flange) insulators is 4 years from the date of production, but does not exceed 6 years from the date of shipment to consumers. The service life of IPU-10/630-7.5 UHL1 (square flange) insulators shall not be less than 25 years.

The storage conditions for insulators IPU-10/630-7.5 UHL1 (method blue) are due to the influence of climate factors in groups 3, 4, and 5. The storage conditions for groups 3 and 4 (non heated storage facilities, sunshades in temperate and cold climates, with no air) allow the insulators to be stored in the manufacturer's packaging, When stored in Group 5 (rain canopy in temperate and cold regions), the insulation must be opened. According to GOST 23216, the complete warranty period does not exceed 2 years.

Produced according to the requirements of GOST 22229-83 using IPU-10/630-7.5 UHL1 insulators (square flanges).
